Bodybuilder Erin Stern in Two-Piece Workout Gear Shares "Abs Exercises"

Erin Stern, a renowned bodybuilder, recently shared a series of effective ab exercises on her Instagram, emphasizing the importance of core strength and precision in execution. Stern’s detailed instructions for exercises like pelvic tilts, single leg lifts, knee-ups, bicycles, and alternating side-ups highlight her dedication to fostering correct form and deep muscle engagement. Accompanied by tips such as maintaining a rounded lower back to better activate the abs, her post serves not only as a workout guide but also as an educational tool for her followers. This focus on technical detail supports her broader fitness philosophy, which integrates strength, stability, and aesthetics, making her a respected voice in the bodybuilding community.

1. She Does Ab Workouts

As you can see from her Instagram post, Stern likes to do ab workouts to stay in shape. The Mayo Clinic states that ab workouts have a lot of benefits. “Your core is the central part of your body. It includes your pelvis, lower back, hips and stomach. The stomach muscles sometimes are called abs. Core exercises train the muscles in your core to work in harmony. This leads to better balance and steadiness, also called stability. Stability is important whether you're on the playing field or doing regular activities. In fact, most sports and other physical activities depend on stable core muscles.”

2. She Uses Weights

Stern likes to use weights to keep herself in shape. She shared this post on Instagram of herself doing exercises with a landmine. Stern captioned the post, “Total body day - landmine edition 💪Workout: Thrusters 3x10. Deadlift 3x6-8. RDLs 3x12. T-bar row 3x10-12. Upright row 3x10 each. Shoulder to shoulder press 2xAMRAP. What did you train today?”

3. She Does Upper Body Workouts

Stern makes sure to do upper body exercises. She shared some of her favorites in this Instagram post. Stern captioned it, “Quick superset arm workout 💪Exercises: Inverse rows (emphasis on biceps). Decline push ups (triceps focused, elbows back & in). Plate hammer curls. Plate overhead triceps extensions. Cable high pulley curls. Triceps push downs (forward lean). I love starting with compound movements, as it helps increase overall calorie burn and hits back and chest. The last triceps exercise hits the long head of the triceps, which can be tough to target!”

4. She Does Cable Workouts

Stern likes to use cable machines to workout. She shared some of her favorites in this Instagram post. “My favorite cable exercises for rear delts 💪Cable crossover reverse flyes. Single arm reverse flyes. Rear delt raise. Rear delt/high rows. For all of these, think about going lighter with higher reps and using full range of motion. If you go heavier, other stronger muscles can take over and form will degrade. If you struggle to feel your rear delts, start with the single arm reverse flyes, and place your non-working hand on your rear delt to feel it working. I like to visualize myself hugging a barrel, and almost stretching my arm to reach across it without flexing at the elbow (keeping the same bend in the arm throughout).”

5. She Does Quad Workouts

Stern doesn’t skip leg day. She shared some of her favorite quad workouts in this Instagram post. Stern captioned it, “Looking for an alternative to leg extensions to build beautiful quads? Try one of these exercises: Reverse Nordic curl. Plank leg extension. Sissy squat. Heel elevated squat. These can also be great home alternatives for building that quad sweep!”
