This week is my second week in CT's superhero-program, and I'm quite enjoying it so far. I also was rather nervous about the program being it "a little" different from TBT 3days a week, but the change in pace is kinda refreshing, to be true. And so far I'm looking forward to each workout and don't have any problems with motivation.
But I did ditch one bicep and one tricep exercise on day 2 for lunges and leg curls. Additionally I replaced one trap exercise on day 3 for 4 sets of calve raises. You can also change the set-rep scheme of the leg work on day 2 of week 1-4 to a more strength oriented approach. And last but not least, don't forget to warm up your shoulders and do some rotator cuff work cause the emphasis on the shoulders is quite taxing.
Overall with some adjustments (more lower body work)an enjoyable program. If you're looking for a pump, you're at the right adress. Though it's too early to be decisive, I can say I don't really have any complaints...(yet?).
Hope this might help.
