- SETUP: Lie flat on the floor and put your heels on a Swiss ball, keeping your legs straight (or a slight bend at the knee if it’s more comfortable).
- REP: Crunch up by squeezing your abs HARD. Your hands should move as if reaching for your knees. Stick a slight pause at the top of each rep for an even better contraction.
- TIP: Start breathing out BEFORE the rep begins. When you get to the top, you’ll feel it 10x more!
