This is absolutely true. I’ve made some damn good progress on cruises and although I’m not at an elite level I don’t see why it wouldn’t apply to most in the PL side. Most of the progress that can be made isn’t just from how much shit can be put in a syringe and shot in a guys ass cheek. Programming, blocks, phases, undulating, MRV etc. All that boring shit. It is invaluable to a powerlifter. Save the blasts for meet preps and get training in order at all times same with nutrition. If a guy wants to lift big numbers there has to be consistent Improvement by way of periodization.
