Hi. This is my first post
Im 14 turning 15 September 9th and am planning to start Sanshou. Im trying to prepare my body to be able to take a beating and survive. However, I recently sustained a rotator cuff injury on my right arm so I am unable to do any excercises with it. Please look through my workouts and see if there is anything else I should to prepare my body. (I do not have access to a gym and am only using my own body weight)

Workout 1:
10 sets x 20 Leg Raises (in between each set i hold an elbow planche for 30 sec. and then continue into the next set)
50 Twisting Crunches
5 sets x 10 Left handed pushups
50 crunches (with legs straight and off the ground)

Workout 2:
10 sets x 10 Squats
5 sets x 20 Standing calf raises
3 sets x 60 second wall sits

Workout 3:
10 sets x 20 Twisting Leg Raises
10 sets x 10 second Supermans
50 Twisting crunches

I only do workouts when I dont feel sore and alternate between sets. Any comments are greatly appreciated.
