Today I moved on to my back exercises.  This is the second week and I can definitely tell that these workouts are killer.

Twisting DB row (ss)
45x12; 50x10; 55x10(f)
Wide lat pulldown (ss)
110x12; 120x10; 125x10(f)

Close grip cable row
120x12; 135x10; 150x8(f)

Bent over row (ss)
95x12; 115x10; 115x8(f)
Close grip lat pulldown (ss)
105x12;120x10; 134x8(f)

What I notice about this progressive overload of the body is that as the rest time decreases I need to also decrease the weight I'm pushing. 

I've also been noticing that my energy levels are up.  I'm not sure why that is, but it is the truth.
