Description

S931 Ab Crunch

Specific product for working out the abdominal muscles and hip flexors. The exercise is performed from a sitting position, with the back and legs firmly positioned against the support pads. It involves flexing the trunk forward so that the shoulders are brought closer to the knees. Resistance is provided by a weight stack which enables the workload to be adjusted to suit each type of user.

  • Converging upper and lower body action engages more core muscles in one natural movement
  • Back support keeps body stable to isolate abdominal muscles
  • Incremental 3.3 & 6.6 lbs (1.5 & 3 kg) micro-loading adjustment
