Heard that! I don’t squat 405 or deadlift heavy stuff anymore. Not worth it and it’s not like I’m a pro athlete. Just wanna toned and lean. Funny thing is I have a little dog and I bent over while playing with him and that’s the moment it set it all off, not attempting heavy lifting
What I’ve learned/confirmed during COVID and no access to the gym is, body weight and high reps with lighter weight can be just as productive for muscle in its own way.
