I'm a pretty large bodybuilder...compete as a SHW at 5'8" and get over 270lb in the offseason. I'm very knowledgable about steroids and nutrition and training but not very fluent in the latest designer chemicals and SARMs and such. Anyway, approaching the offseason and getting over 270lb puts a toll on the heart and cardiovascular performance and endurance in the gym. I specifically am looking to decrease my rest times between sets and would like my cardiovascular endurance to not be the limiting factor during heavy leg sessions and such. To those who have experience with cardarine....will this make a significant difference? I'm not looking for an easier time on the treadmill or whatever..just more endurance during weight lifting sessions.
