Demo (loops)

How to do it

Starting position

  1. Sit on the floor, bend your knees, and place your feet on the floor.
  2. Lean your upper body back slightly to create tension in your abs.
  3. Hold the medicine ball firmly in front of your chest with both hands.

Movement

  1. Slowly rotate your upper body to the right.
  2. Pause briefly, then rotate to the opposite side, the left.
  3. Alternate sides and repeat for the designated number of reps.

Breathing

Exhale as you rotate and inhale as you return to center.

Trainer tips

  • Keep your chest up and keep your back straight
  • Move the ball from side to side, following it with your eyes
  • Rotate with your obliques and keep your pelvis fixed

Cautions

  • If your back rounds, it loads your lumbar spine and can cause pain, so tighten your abs.
  • If you twist quickly using momentum, it strains your lower back, so control your speed.
  • Swinging the ball side to side with only the arms

How GYMKC sets the weight for this exercise

This exercise starts with your bodyweight. Once you reach 12–20 reps, you add weight in 2.5 kg (5 lb) steps.

GYMKC adds reps before weight. The sets you log also decide when it is time to add weight.

These numbers are an example of how the calculation works. Your actual prescription is recalculated every set from your own records. See how the calculation works
