If you workout 15-30 minutes then I would aim for three or four times per week. If your workouts are 45-60 minutes or more then two or three per week should be ample! It is a good idea to wait till you have stopped aching to train again especially if you are fairly new to lifting weights.
The workout below consists of five easy exercises: 45 seconds work, 15 seconds rest
1) Squat and Press
2) T balance
3) T balance (other leg)
x3
4) Reverse Lunges
5) Bent over row
