I bought this PDF with this ab training program and it says for incline twisting situps â??2 sets â?? 12 reps, 8 reps, 10 repsâ?? I donâ??t know what it means. I canâ??t contact them, whenever I send them an email they donâ??t reply. Do you think it means 2 sets of 12 reps, 2 sets of 8 reps, and 2 sets of 10 reps?
