Don’t worry about the others in the gym give your self some time, depending upon your age, etc, but nothing exciting is going to happened before Christmas,
Remember if you have been out of the gym and do a cycle soon, only the muscle grows and everything else is vulnerable to injury, joints, tendons, cartilage,
So take it easy. Remember those tendon tears just don’t heal like they use to,
Your better off to go moderately the first few months and let everything grow together.
I hear you, it is up and down
Yesterday I was doing dumbbell presses with 10lbs, normally 75-85, just said forget it and did cardio,
So it comes and goes, but the good days make up for the bad.
