Trainer tips

  • Support one dumbbell with both hands
  • Keep your elbows pinned next to your ears
  • Lower deep behind your head to stretch

Cautions

  • Overarching your lower back risks spinal injury, so brace your abs.
  • Flaring the elbows out to the sides

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 10 reps with 16 kg and log that you could have done about 2 more, GYMKC estimates your 1RM at about 23.1 kg.

With the dumbbell, it moves up to the next weight you have. Within your 10–15 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
