After finally recovering from severe COVID19, I want to return to work in EMS. However, I'm a small person - just over 125 lbs myself. I used to be able to lift 125 lbs without difficulty, but it's been almost a year and most of that time I was really sick (I literally died). I can't afford a gym membership. Does anyone have any suggestions for workout routines, apps, YouTube channels, or sports that are cheap/free and involve lifting and upper body strength?
