My current workout schedule is 5 straight days. 3 days upper body weights, 2 days elliptical and abs, alternating days. I was reading up on how alternating sets is best if you want to increase the weight you lift because you work more muscles at high energy, and I was wondering if that principle applies to working the same area over multiple days.
For example, on weight days, I currently do (all dumbbell) bench press/one arm rows, lying flys/triceps kickback, shoulder press/bicep curls, and lateral raises/upright rows. On ab days I do flat and side planks, mountain climbers, reverse crunches, trunk rotations and glute lifts.
Would my workout benefit if I switched it up and alternated the weight training days to do some upper body weights and some abs 3 days a week instead of upper body 3 days and abs 2?
