As a personal trainer, I'm often asked about the best exercises for abs. The truth is, the most effective ab exercises aren’t just about doing endless crunches – they’re the moves that research shows truly engage your core muscles. Below, I’ll cover the top five abs exercises I recommend to clients, backed by science (like EMG studies and fitness research), and explain why each one earns its spot on the list. Let’s get started on strengthening that core!
Top 5 Best Ab Exercises (Backed by Science)
Dead Bug – This deceptively simple exercise is a personal favorite for building core stability. You lie on your back with arms and legs in the air, then slowly lower one arm and the opposite leg, alternating sides. The dead bug forces you to brace your abs and keep your lower back flat, which strengthens your core while minimizing spine strain. In fact, studies show the dead bug is highly effective for trunk and pelvis stabilization, activating multiple core muscles (rectus abdominis, obliques, and deep stabilizers) as you move your limbs (acefitness.org). Because it focuses on controlled, isometric contractions (no jerky motions), it helps reduce injury risk and builds spinal stability (nsca.com). In other words, the dead bug teaches you to engage your abs properly – an essential skill for safe, effective ab training.
Forearm Plank – You’ve probably done planks before, and there’s a good reason they’re so popular. A forearm plank (holding a push-up position on your forearms) is an isometric exercise that engages your entire core. Research confirms that planks intensely activate the transverse abdominis (deep core muscle) along with the obliques, while also working the rectus abdominis to maintain a flat posture (pubmed.ncbi.nlm.nih.gov). In plain terms, a plank teaches your abs to brace and endure. Plus, unlike crunches, a proper plank also calls on your shoulders, back, and glutes to hold your body in alignment, giving you a true full-core workout. This exercise is fantastic for building core endurance and stability – think of it as the foundation for a strong midsection that will support you in everything from heavy lifts to daily activities.
Cable Straight-Arm Rotations – This exercise (often done on a cable machine or with a resistance band) targets your obliques and deep core muscles through controlled rotation. You stand holding a cable with arms straight in front of you, and then rotate your torso to pull the cable across your body. I love cable rotations because they’re functional – they mimic the twisting motions we use in sports and daily life, while training the core to resist unwanted movement. Fitness experts note that doing standing cable rotations engages your stabilizer muscles naturally (exrx.net). In practice, this means your obliques work overtime to control the movement, helping carve out a strong, defined waist. By keeping your arms extended, you put more load on the abs (instead of relying on your arms), making straight-arm cable rotations a top exercise for building rotational core strength and a stable spine.
Hanging Leg Raises – When it comes to lower abs, hanging leg raises are hard to beat. This exercise involves hanging from a pull-up bar (or using a captain’s chair apparatus) and lifting your legs or knees up toward your chest. It’s challenging, but incredibly effective – multiple EMG studies have found hanging leg raises to be a top-tier abs exercise, ranking high in activation for both the rectus abdominis and obliques (menshealth.com). By initiating the movement with a pelvic tilt (curling your hips up), you really zero in on the lower portion of your abs. Hanging leg raises also engage the obliques and even your hip flexors to a degree, making them a great compound core move (t-nation.com). As a trainer, I emphasize form here: raise and lower your legs in a controlled manner (no swinging!) to get the most muscle engagement. When done right, hanging leg raises can help sculpt the lower abs and build serious core strength.
Ab Wheel Rollouts – Last but definitely not least is the ab wheel rollout. If you really want to test your core, this small wheel with handles will do it! From a kneeling position, you roll the wheel forward and back, keeping your core tight so your body stays straight. The rollout is essentially a moving plank, and it demands tremendous core strength to prevent your lower back from sagging. Research has shown that ab wheel rollouts are among the top exercises for activating the abs – one study found the rollout produced extremely high activation in the rectus abdominis and overall core (strengthandconditioningresearch.com). It even engages other muscles like your lats and shoulders as you stabilize yourself (breakingmuscle.com). This exercise teaches your abs to brace during an extended position (which is super useful for real-life lifting and sports). I always remind clients to start with kneeling rollouts and focus on form: only roll out as far as you can maintain a flat back. With practice, ab wheel rollouts will significantly strengthen your abs and improve core stability, earning their place among the best exercises for abs.
Conclusion and Expert Tip
Incorporating these top five ab exercises into your routine will work all parts of your core – upper abs, lower abs, obliques, and the deep stabilizers. Remember, quality beats quantity: focus on form and controlled movements to really feel those abs working. Consistency is key, and so is pairing core training with good nutrition and overall fitness habits for the best results.
