What’s the Best Exercise for Abs?

Everyone wants to know the best ab exercise—especially as warmer weather approaches.

Here’s the truth: there’s no magic movement that will give you a six-pack overnight. But if you want to strengthen your core, lose body fat, and improve muscle definition, here’s what actually works.

1. Nutrition Comes First

If you’ve ever heard the phrase “abs are made in the kitchen,” it’s true. Everyone has abdominal muscles, but whether you can see them comes down to body fat levels and genetics.

Eating the right foods to support your training—without storing excess fat—is key. That doesn’t mean extreme diets or cutting out entire food groups. It means eating in a way that fuels your workouts and aligns with your goals.

A nutrition coach can help you figure out what works best for your body, but a good starting point is focusing on whole, unprocessed foods with plenty of protein, fiber, and healthy fats while keeping sugar and processed junk to a minimum.

2. Train with Full-Body, Compound Movements

Forget spending hours on ab workouts—most of your core strength will come from big, functional movements that force your core to work as part of a team.

When you use machines like leg extensions or bicep curls, your core isn’t doing much. But when you squat, deadlift, press, or carry weights, your abs, obliques, and lower back are all engaged to keep your body stable.

Think about a standing overhead press: to keep the weights balanced over your head, your core has to brace and hold you upright. Or take a heavy back squat—your abs and spinal erectors are working hard to keep your torso strong as you move. These movements do far more for core strength than endless crunches.

3. Add Direct Core Work (But Make It Count)

Core exercises absolutely have a place in your training, but they should complement—not replace—big lifts and proper nutrition.

Instead of just doing sit-ups, mix in exercises that target different parts of your core:

For overall core stability: Planks (front and side), ab roll-outs, bird dogs, Turkish get-ups
For rotational strength: Russian twists, wood choppers, side bends
For lower abs & hip flexors: Hanging knee raises, flutter kicks, V-ups
For posterior chain & glutes: Glute bridges, reverse hypers

A simple way to structure core training is to choose one movement for the front (e.g., bicycle crunches), one for the sides (e.g., side planks), and one for the back (e.g., glute bridges). Start with 1-3 sets of 8-12 reps, two to three times per week, with a rest day in between.

The Takeaway

The best way to build strong, defined abs isn’t by doing hundreds of crunches. It’s by training smart:

Eat well to support muscle definition
Lift heavy and use full-body movements that build natural core strength
Supplement with core exercises that hit different angles

There’s no one-size-fits-all approach, but if you need help, a coach can give you a strategy that works for your body and your goals.
