Since dropping Tri-Max and adding M1T to my Sldge Test/1-Test-cyp cycle , I can hardly make it through a 45 min workout anymore. The few sets I get done are incredibly intense, and far exceed the previous week's workout. I get cartoon character/lat syndrome pumps and after 6-8 sets I have to leave the gym because I can barely move. 45min has been the longest I've worked out in a while now, usually anywhere from 25-40min. I used to train 1hr, no more no less, every session. Yesterday I squatted, and I've been doing sets of 5 for about 4 months or more now, and they've been kinda stagnant as of late. I built up to 335X5 about 4 weeks ago and haven't gone up since. So I dropped it to 275, and hit sets of 12, 10, and then 225X12. I did one set of leg extensions, then did a set of cable side bends (obliques). At this point my lower back was so pumped that I could hardly walk (not to mention the agonizing pain), so I left after only 25min. So here's the question... What should I do (if anything) to compensate for the lower volume (mind you the intensity is unreal, for me)? Should I up the frequency, lift different muscle groups twice a day, or just keep other factors the same and hope that the extra intensity will pay off?
