Just finished week 3 of the Giant 1.0. I'm really pretty stoked about this program. I did the 2.0 first as I felt a "break in period" with higher reps than I was used to would be a good idea and the ladders made it a bit more tolerable.
Geoff Neupert advised me that although that idea of using the 2.0 first using ladders was certainly doable, I'd probably be shocked at the difficulty of straight sets.....he was dead right! Straight sets in a density type plan just plain suck! To give an idea, today was day three of week three. On day three of week one I got 50 total reps in 30:00. Today I got 80 reps! In addition, my heart rate today actually stayed lower than it did a couple of weeks ago doing much less volume! I gotta say I'm my mind that's great progress!
Next week is the final week of 1.0 and I'm going to do a deload of sorts, just going for 20 minutes rather than 30.
This program (s) rocks!
