Do you know the Rolls Royce of the abs machines ?

Forget everything you can find on the market, this is the perfect equipment to really isolate the abs.
The device forces you to recruit your hamstrings and glutes instead your hip flexors.
When you do sit ups, even crunches, hip flexors are often overworked and involve low back pain.
The activation of the glutes and hamstrings inhibits the hip flexors, so the abdominal muscles have no other choice to work alone.
It means a harder muscular tension, less reps and more results.

Less time, more results, safer : check it here !
