THOU SHALT…

Focus on full-body exercises

And curtail targeted ones. A new study found that moves that recruit the delts and glutes (like the bird dog, opposite) create more ab activation than crunches. Plus, total body moves like deadlifts burn more fat.

Practise crocodile breathing

Why? Because it engages your abs more. How? Lie on your front with your hands under your forehead. In this position, inhale through your nose, filling your abdomen (not chest), for five seconds, hold for one, then exhale for three. You can also try it while working out, exhaling during the exertion part of the move.

Do chest openers

Exercises that work the back and open the front of the body will improve your core strength and posture by firing up your glutes and the muscles along your spine. And these moves tend to retract your head (which pokes forward most of the day, putting pressure on your midsection).
