3. KNEE-STANDING FORWARD ROLL WITH BALL

3 series, 15 reps Stand on your knees and lean against the ball. This is your starting position. Flex your abdomen and lower back. Then, roll forward. Hold on there for 3 to 5 seconds. Return to the initial position before the load exceeds your strength. This is one rep.

4. REVERSE SIT-UPS

3 series, 15 reps Instead of the normal sit-up, where you would go up, in this case you’ll go down. It’s important that you go down just until the moment where you feel you’re going to lose control. Keep your back straight.
