Movement

Trainer tips

  • Hold the kettlebell in front of your chest with both hands
  • Lean your upper body back slightly and hold
  • Rotate your entire torso side to side

Cautions

  • Rounding your back can cause a lumbar injury, so keep your chest up.
  • Swinging only the arms side to side
  • Slouching and rounding the back

If you feel pain during the exercise, stop. If it continues, talk to a professional.

How GYMKC sets the weight for this exercise

For example, if you do 8 reps with 16 kg and log that you could have done about 2 more, GYMKC estimates your 1RM at about 21.7 kg.

With the kettlebell, it moves up to the next weight you have. Within your 8–12 reps target, the sets you log decide whether to add reps first or 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
