I'm trying to follow the WBB #1 routine as closely as possible.
I've made two changes:
1) Dumbbell flat bench instead of barbell. My left pec is bigger than my right; I'm trying to balance them out.
2) Seated calf machine instead of standing. My calves are pretty strong and it stresses me out to have all of that weight on my shoulders (there's no standing calf machine).
Are either of those changes problematic?
