I had a very bad injury to my leg and it kept me out of the gym for the better part of 2 years. I’ve put a bit of weight on since then and I’m just wondering what the best strategy for me to recomp is? I’ve been going to the gym 4 times a week for the last 2 weeks, eating in a ~500kcal deficit, hitting 150g protein per day aswell. But the reason for this post was because both yesterday and today I was significantly weaker than the last 2 weeks. Is this normal? Am I doing something wrong or has it just been a bad couple days in the gym?
