Caporegime
Delvis trains at home.
Though some bulgarian split squats, even at body weight could be good. Nice and slow. You could hold the dumbell in the opposite hand. Though doing this regulary may create some imbalances and lead to problems further down the line.
Aye
Possibly...but that would have hurt, even in the opposite hand Which is why I'm thinking color bone injury originally, but god knows...it'd be still as painful now unless i heal REALLY quickly
Bodyweight, deep squat jumps
dude...it was hurting to walk! Let alone squat
