4 Push-up Mistakes Beginners Make According to Expert

Alexia Clark’s abs are on fire – and she is revealing a few of the ways that she achieves them. In a new workout video shared to social media, the trainer and influencer reveals her chiseled midsection during an ab workout, and reveals a few ab mistakes that people are making. “Do you feel like you haven’t made much progress with your core?” she captioned the Instagram post, adding “Here’s why your core routine is ineffective,” in the clip. Her followers went wild. “You are bad a$$ and look awesome!” commented one. “My girl kills it every time 🔥❤️,” added another. Here are a few of the mistakes you are making, according to Alexia, and a few additional tips she has for strengthening your midsection.

Mistake One: You Are Trying to Look Cool on Social Media

Alexia maintains that a lot of the ab workouts shared on social media were made for likes – not effectiveness. “The core routines you are choosing are just for ‘show’ on Instagram and really don’t do anything at all except look cool,” she writes.

Mistake Two: You Aren’t Engaging Your Core

A big part of any exercise is engaging the right muscles – especially the core. A big mistake is “you are neglecting engaging your core in EVERY EXERCISE,” says Alexia. “A lot of people don’t realize that every exercise is a core exercise. You HAVE to keep your core engaged. (Even during cardio).”

Mistake Three: Too Much Repetition

Are you doing 100 crunches every day, but nothing else? According to Alexia, “doing the same thing over and over again,” is a huge mistake when it comes to your abs. “If your program has you doing a 30 second for 12 weeks your body is just learning to tolerate a 30 second plank. You have to introduce new challenges all the time,” she says.

Use a Bosu Ball

Alexia often uses a bosu ball for ab work. “If you don’t have a bosu ball you can do all of these on a mat! The bosu ball adds some extra stability challenge to mix things up!” she said in one of her ab workout videos.

You've been consistent with your workouts, pushing yourself harder every week. But instead of seeing that lean, defined physique you're after, something feels off. Your clothes fit differently, your muscles look bigger rather than toned, and that coveted athletic look seems further away than ever. These are frustrations realistic fitness dietitianDenvyr sees in her practice every day.

Denvyr knows these struggles intimately. As a former volleyball player who transformed her own relationship with food and exercise, she's experienced the journey firsthand. After overcoming binge eating and studying the science of sustainable body recomposition, she now helps clients build bodies they love without sacrificing their relationship with food. "I've made all these mistakes myself," she reveals, "and that's exactly why I can help others avoid them." Read on to discover the ten most common workout mistakes that could be sabotaging your results, and learn the science-backed solutions that will finally help you achieve that lean, toned look you're after.

Mistake: Obsessing Over Weight Instead of Fat Loss

"Weight can mean many things—muscle mass, water, bone mass, not just fat mass," Denvyr explains in the post. She points out that if you gain a pound of muscle while losing a pound of fat, the scale won't budge, but your body will look leaner and more toned. "Fad diets may help you lose weight quickly, but you're actually losing more muscle than fat mass most of the time," she warns.

Mistake: Eating More Than You Realize

One major reason for unwanted bulk, according to Denvyr, is consuming more calories than your body burns. "When you start training for the first time, hunger increases," she explains. This natural increase in appetite, combined with factors like insufficient sleep and excessive cardio, can lead to unintentional overeating.

Mistake: Skimping on Sleep

"At least seven hours of high quality sleep where you feel rested is the goal," Denvyr emphasizes. She shares from experience: "I have photos of myself where, despite working out so hard, I looked really inflamed and bloated because of poor recovery. Sleep isn't just about rest—it's crucial for achieving that lean look."

Mistake: Getting Your Macros Wrong

"Protein is king for fat loss and looking lean," Denvyr states. She recommends aiming for at least 100 grams of protein daily, eventually working up to one gram per pound of body weight. However, she warns against completely restricting carbs and fats: "I made that mistake before. Although I looked very lean, I was fatigued every single day. My performance was absolutely terrible, and I couldn't function without thinking about food 24/7."

Mistake: Following Random Workouts

Random workouts aren't the answer, says Denvyr. "You should be following a structured training program that helps you progress every week, every month, for years," she emphasizes. "If you're doing random workouts from Instagram or YouTube with very light weights, that's actually an endurance style of training. Your body will quickly adapt, and progress will stall."

Mistake: Ignoring Stress Levels

Denvyr notes that elevated cortisol from lack of sleep, food restriction, or overtraining can create unwanted bulk. "Although exercise can temporarily increase cortisol, it's the chronic elevation that becomes an issue," she explains. "I have definitely had my fair share of experiences with running myself into the ground. This mentality ends up causing us harm because we don't know when to slow down and rest."

Mistake: Overdoing Cardio

"If you're one of my clients, I only recommend one to three days of cardio max in the week on top of your strength training," Denvyr shares. "If you're adding lots of running and intense HIIT training to your weeks, your body is just trying to keep up with you and make sure you're fed well enough so you can recover."

Mistake: Staying Too Sedentary

For desk job workers, Denvyr recommends adding 2,000-3,000 extra steps daily. "You don't have to walk 30 minutes all at once," she suggests. "I like to walk in the morning, so I do 10 minutes then, 10 minutes after lunch—which can help with digestion and blood sugar balance—and another walk in the evening."

Mistake: Relying Only on the Scale

"Make sure you're taking photos of yourself, taking measurements, and paying attention to how different parts of your body are shaping," Denvyr advises. "Maybe your butt is growing. Also, pay attention to the way that you feel. Pay attention to what your body is telling you. The scale is just one small piece of the puzzle."

Mistake: Expecting Overnight Results

"Body recomposition takes time," Denvyr emphasizes. "This way of training allows you to have food freedom. You're able to eat the foods that you love in a mindful way, and you're getting stronger. You're appreciating your body more, you're feeling good in your body. When you start paying attention to progress beyond just body aesthetics, that's when you truly become fit for life."

Whether you are a triathlete, runner, cyclist, surfer, mom, or dad, strength training is critical to overall health and a triathlete’s training regimen. I would know. I received my education in a Master's Degree in Science with an emphasis in Exercise Science from the University of Texas in San Antonio. Before receiving my Master's Degree, I participated in 4 Ironman Triathlons, a 2.4-mile swim, a 112-mile bike, and a 26.2-mile run, but I wanted to learn more about the "why" and the "how" through knowledge. While getting my Master's Degree, I coached CrossFit but where it gets good is learning about my knowledge of strength during my Ironman Triathlon training and beyond, as so many triathletes will push the strength training aside. My goal with my triathletes and runners is to keep the muscle on as long as possible before heading into the heavy specific training for a race.

Why should strength training be incorporated into the everyday healthy human? As discussed here, strength training will improve bone density, increase muscle strength and endurance, help build lean muscle, and improve overall quality of life. Let’s get into a little more detail about Strength Training for Triathletes as I'll outline five key strength-training exercises for triathletes: squats, push-ups, core work through Hollow Rocks, back squats, and a combination of leg presses and lunges to build a robust and efficient athletic physique.

The Benefits of Strength Training

Did you know that adding strength training for endurance athletes will help them get faster in their races and training? Strength training will increase leg strength and improve your body’s efficiency in using energy and oxygen. Studies (see below) have shown that athletes who embark on an 8-week strength training program will increase their Running Efficiency (RE). What is RE? Running efficiency is using less energy at a faster speed but with proper running form.

Initial Steps to Take Before Strength Training

First, ensure you understand the exercises and gym equipment. When I work with my clients, I make sure they know basic movements well before I add weight to their program.

Next, if you don’t feel comfortable in the gym, I would sign up with a personal trainer, a boutique-style gym, or a CrossFit gym to provide and show that you are doing the exercises correctly.

If you know the exercises and how to use the machine and bars, you can reach out to me directly here to start a training program designed for your triathlon, or you can look online for other personal trainers to help you with a workout designed for your life.

My First Strength Training Exercises for Aspiring Triathletes

A triathlete should focus on exercises that target the major muscle groups used in the swim, bike, and run. Most of these muscle groups are similar. As a coach, I will include exercises such as squats, deadlifts, leg presses, and lunges for the lower body. For the upper body, I will have them focus on pull-ups, chin-ups, rows, lat pull-downs, or seated rows on the machine. Of course, having a solid core with planks and crunches is a bonus! Let me explain three exercises to help the triathlete build their body into a robust and fast machine.

Squats

Squats are fantastic for targeting many leg muscles, such as quadriceps, glutes, and hamstrings. There are many options, such as air squats, back squats, dumbbell squats, goblet squats, and so on, so squats are one of my favorite exercises for the lower body.

Five Key Points to a Back Squat

1. The shoulders and hips are aligned. The feet are slightly past the hip position, and the toes are turned out. The core is engaged. (Ladies, your hips are not that wide!)
2. Only go down as low as you feel comfortable. If you need a box or a bench to tap while doing the squat, that is fine, but no sitting!
3. ​Make sure you are comfortable going into a squat position before you put any load on your back for a back squat.
4. If you are uncomfortable going into a back squat, there are other options for squats: Air squats, goblet squats, front squats, and Overhead Squats (Advanced). You have to do what is BEST for you!
5. Make sure you get a proper warm-up when performing squats. Activate the glutes, quadriceps, and hamstrings, but remember the shoulders and traps, as the bar is on the back.

Push Ups

Push-ups can be a challenge for many, but push-ups will also use many of the muscle groups that are great for swimmers and have a more muscular upper body for cycling and running. The muscles used in push-ups are the pectoral muscles, core, bicep, tricep, and shoulders.

Five Key Points to a Push-Up

1. Close-handed push-ups involve aligning your hands with your shoulders. Wide-handed push-ups are another option. You have to figure out which works best for you.
2. Make sure your scapulas (shoulder blades) are in a neutral position. When you do a push-up, we want them to move toward the center.
3. Keep your core, lower back, legs, and glutes engaged and tight at the top and bottom of the movement.
4. When lowering your chest to the ground, the scapula will move toward the spine. Ideally, the chest should touch the ground. When you return, we want to see a full extension in the arms.
5. That is fine if you need to go to your knees for a push-up. We still want to see "Rules" #3 and #4 when doing the push-ups.

Core Work

Core work is tricky because sit-ups are only the end-all for some athletes. I have an athlete who can not do sit-ups due to her back, so I have to develop new workouts to help her with her core. The same may apply to you. My favorite exercise for abs is Hollow Rocks, and if you can advance it, then V-Ups are fantastic, but let’s discuss Hollow Rocks.

Five Key Points to Hollow Rocks

1. Make sure your lower back is genuinely engaging with the floor. It should stay in contact with the ground.
2. Lift shoulders off the ground, then lift legs off the ground and keep them bent at a 90-degree angle.
3. Start rocking back and forth through the hip to the bottom of the shoulder blades. Think of your joints NOT moving. Look at your feet.
4. Once you master the “basic 1, 2, and 3” movements, you can advance. The first advancement is a single-leg extension. Work on holding the movement and then adding the rocking movement.
5. Once you get 1 - 4 down, let’s add both legs. Practice holding first with both legs and then start rocking.

Common Pitfalls to Avoid

We addressed some mistakes that people should avoid when starting strength training, but here are a couple of mistakes that people should avoid for long-term growth in and out of the gym.

1. Increasing your weights too fast: Many people go into the gym and "remember" the time they had a PR squat or deadlift, which may have been in high school and will try to start with that mentality immediately. Slow down, friends! As coaches or trainers, we want to improve your strength gradually. You don't lose your strength overnight and gain it overnight.
2. Time To Recover: Rest is vital, whether you have a day off during the week or take time off between upper and lower body days. Make sure you schedule a day off during the week. Contact a coach or personal trainer if you are still determining when to take it off.
3. Improper Technique: Proper form can make or break you during strength training. It may look different if you need better form, and try adding weights. Make sure you work with someone who knows how to teach the form or watch videos that can show you how to do the form correctly. If you have a friend who can film you, you can also give yourself feedback or show your coach or personal trainer.
4. Overtraining: Many do this, and many fail. When an athlete, runner, or fitness enthusiast doesn't recover after tough sessions, this can lead to injury, sickness, poor performance, and fatigue.

Final Word From the 15x Ironman Triathlete

coachjenrulon/Instagram

It is a delicate balance when it comes to strength training and getting ready for your triathlon. There will be off-seasons for triathlon training, during which you will incorporate more strength training, and when you are closer to races, you will pull back on your strength training.

As a 15x Ironman Triathlete and a coach for many triathletes, I ALWAYS remind them to have fun. We get to do this. We choose to do this. When I work with athletes getting ready for their first triathlon or Ironman Triathlon, I remind them that this will be their FIRST-ever event, and they will never get that feeling back.

Jen Rulon's transformation from a 15x Ironman triathlete to an everyday healthy human unfolded through a blend of strength training, walks, healthy eating, meditation, surfing, journaling, setting boundaries, and embracing life in Costa Rica, embodying her passion for fitness and authentic living.
