So you want to really work your legs but have no equipment, limited space and even less time? Try Alywn Cosgrove's LEG MATRIX:
1. 20 Bodyweight Squats
2. 20 Lunges (10 on each leg)
3. 20 Jumping Lunges (10 on each leg)
4. 20 Jump Squats
Take 90 secs recovery and repeat.Take 90 secs recovery and repeat (or collapse onto floor...)
This is a terrific "finisher" after a workout or as a standalone metabolic workout.
Have fun !
