I hope you are okay 😰 Squats are a realky good exercise to make your legs stronger. Maybe swimming, but if your hurt your collarbone maybe is not a good idea 😅 So, as Grace says, you can also try walking and jogging!
That may help gain back your stamina
Ahh just try maybe doing like a 30 min walk every day building up to an hour then maybe do a 30min jog
I fractured my collarbone
Depends what the injury is ??
