Machine Seated Twist
How to do it
Starting position
- Sit on the seat and plant your feet firmly on the floor.
- Press your thighs and pelvis firmly against the pads to secure them.
- Grip the handles firmly with both hands.
Movement
- Engage your abs and rotate to one side.
- Pause briefly at the peak to feel the contraction.
- Slowly return to the starting position.
Breathing
Exhale as you rotate and inhale as you return.
Trainer tips
- Secure your pelvis and legs with the pads
- Keep your chest up and rotate only your torso
- Slowly resist on the way back
Cautions
- Using momentum can cause a lumbar injury, so move slowly.
- Pushing with the arms to rotate the torso
- Twisting with the lower back past the range of motion

How GYMKC sets the weight for this exercise
For example, if you do 10 reps with 40 kg and log that you could have done about 2 more, GYMKC estimates your 1RM at about 57.6 kg.
With the ab crunch machine, each step is 5 kg (10 lb), so the next weight is 45 kg. 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
