Here are my top Ten (body weight) strength training exercises (no machines necessary):

1. Hindu Squats – Great quad power builder and aerobic work – build up to 200 reps.

2. Squat Thrusts – These are killer – see if you can build up to 75-100 (good form).

3. Wall Sit - Build to 2 minutes.

4. Pushups – There are so many different ways to do them. 

5. Plank – build up to hold for 3 minutes and your abs will be very strong.

6. Jump Rope (speed sessions) – build up to 5 minutes. 

7. Reverse Crunch – Build to a set of 50.

8. Mountain Climbers – Build up to 100 total (50 for each leg).

9. Superman – Build to a set of 20 “holds”. 

10. Bicycle Crunch - Build to 1 minute (fast and high rev’s per minute).
