The two excerises that are together will be superseted together, with about 30-45 seconds rest between each paired set. I want to stay in the gym for about 45 min. I will be doing morning cardio for about 30-45 min in the morning three days a week. Abs three days a week. The reason for the superset if b/c I have been doing htem here lately and absoutly love them. Great pumps, great burn, and shorter gym time. Please Critique!!!!
