HEY BOOKIE, I suffered from a ruptured tendon and so I know the limitations. I coach one on one boxing pad class, which would get you fit and teach you to fight in the process.
If interested its £15 for 45 minutes plus travel.
PS... I was taught by Brendan Ingle who taught many world champions, British and European champions, such as current champion Kell Brook.
Call me on 07473152619.
Peace & Blessings
