Instructions
3/4 Sit-Up
Lie down on the floor and secure your feet. Your legs should be bent at the knees.
Place your hands behind or to the side of your head. You will begin with your back on the ground. This will be your starting position.
Flex your hips and spine to raise your torso toward your knees.
At the top of the contraction your torso should be perpendicular to the ground. Reverse the motion, going only ¾ of the way down.
Repeat for the recommended amount of repetitions.
One-Arm High-Pulley Cable Side Bends
Connect a standard handle to a tower. Move cable to highest pulley position.
Stand with side to cable. With one hand, reach up and grab handle with underhand grip.
Pull down cable until elbow touches your side and the handle is by your shoulder.
Position feet hip-width apart. Place free hand on hip to help gauge pivot point.
Keep arm in static position. Contract oblique to bring the weight down in a side crunch.
Once you reach maximum contraction, slowly release the weight to the starting position. The weight stack should never be unloaded in a resting position. The aim is constant tension during the set.
Repeat to failure.
Then, reposition and repeat the same series of movements on the opposite side.
