I have a torn abductor in my groin and have been very easy on my training for a month or so. Can you suggest any excercises that can help to strengthen this?

Sorry to hear about your torn adductor. You said abductor in your e-mail but if it's in your groin it is probably your adductor. Once you have been cleared by your doctor you can begin doing Side Lying Leg Adduction with 1-3 sets of 12-15 repetitions. Then, after two weeks of doing this you can begin with some resisted movements like Machine Leg Adduction. Do 1-3 sets of 8-12 repetitions. Then, two weeks later again, you can start with Barbell or Dumbbell Side Lunges. Once you have been through this six week series you should be able to resume a normal program again with squats etc.
