Hardcore training requires knowing how to eat properly. One of the biggest mistakes a lot of bodybuilders make is to fall for the belief that even the best nutrition plan can override the need for proper rest. Rest allows catabolic hormones – those that fight muscle growth – to recede. While good nutrition also suppresses catabolic hormones, there’s a limit to how effective your nutrition will go. From there, it’s all about rest. If you find yourself skipping the mistakes I outlined and still failing to add quality beef, that means you need more rest days. Instead of triggering your body to grow, you’re hammering it too hard and even the ideal nutrition scenario can’t save you. I’d suggest taking a closer look at your training and adding another rest day or two to your current training regimen.
