This is part of the Men’s Health Body Bible, a collection of cutting-edge stories focused on helping you build more muscle using the latest science and lessons from some of the finest athletes and trainers on the planet.

THE SECRET TO training your abs is out—and it entails more than situps and planks, more than just targeting your rectus abdominis, the ballyhooed band of muscle between your chest and your hips. If you want true core strength (and, yes, that six-pack), a growing group of experts will tell you that you need to carry heavy weights and walk. This forces your core to constantly microcorrect and rebalance as you move, explains Aaron Horschig, C.S.C.S., D.P.T., a St. Louis–based physical therapist. You also need to twist and turn, challenging your oblique muscles and back extensors.

“While there’s nothing wrong with training the abs for show, training for stability—which encompasses all of the muscles that surround the spine and hips—is essential training for everyone,” says Horschig. His new book, Rebuilding Milo, includes a variety of exercises, many of which challenge your entire core—think lower back extensors, glutes, and obliques, which all team up with your abs to stabilize and bolster your back, lending postural support.

Unlike body parts that handle just one or two tasks (like your biceps, which are most heavily utilized to bend your elbows), all those core muscles have a host of responsibilities. They work together to flex your spine (as happens during a classic situp), and they help rotate your shoulders so you can turn to look at a friend. They also prevent excessive rounding of the lower back (known as anti-flexion), a key tactic in the battle to stop back pain. The ideal abs regimen trains all these functions, protecting you against injuries and readying your core (and spine) for anything life can throw at you. Horschig says people finally get that. “More and more people are starting to understand the true role of core,” he says.

The end result of all this work? A lower back that’s armor-plated against persistent pain, and the ability to move athletically and fluidly. And along the way, you’ll build those six-pack abs, too.

plank shoulder tap

Plank Shoulder Tap

An underrated plank upgrade, this move challenges your abs and obliques (and your glutes, too!). Start in pushup position, feet wide. Lift your left hand and touch it to your right shoulder. Keep your hips square as you do. Repeat on the other side.

Work for time, not reps, doing three 40-second sets.

Split-Stance Cable Chop

Stand in a split stance, left shoulder next to the high pulley of a cable machine, both hands grasping the handle, then bend at the knees until your left thigh is nearly parallel to the floor. Keep your hips square to the front as you pull the cable across your body, then return it to the start.

Do 10 to 12 reps per side. Do 3 sets.

Mixed-Rack Carry

Stand holding kettlebells in both hands, the left bell at your chest, the right bell at your hip. Walk forward (or march in place) for 10 to 15 steps per leg. Move slowly, working to keep your hips square.

Do 2 sets per side, challenging your abs and lower-back muscles to keep you upright against the heavy load.

The Ultimate Abs Cheat Code

TRAIN YOUR ABS EVERYDAY. Some muscle groups require several days to recover, but your core muscles are built to be resilient. That means you can train them nearly every day. Consider doing 3 or 4 sets of core work in every work- out, rotating in new and different ab exercises to continually challenge your rectus abdominis, oblique muscles, and lower-back spinal erectors.

Biggest Workout Mistake

NEVER GOING HEAVY. Bodyweight planks and situps are a solid starting point for your ab training. But just like any other muscle, core muscles are meant to be loaded and overloaded. Add resistance to your core training, and don’t be afraid to challenge yourself, especially on moves like the mixed-rack carry above. “You have to do that sometimes,” says the popular bodybuilder and trainer known as Ulisses Jr. “I’d be lying if I told you I didn’t load my abs.”
