Who knew a paper towel could give such a great workout. Don't over look these things. You WILL be sore.
3 Sets of 30 reps for each leg.
1- Reverse Glider Lunges: really try and keep the weight in that heel as you pull yourself up instead of using the toes or front part of the foot.
2- Slide Glider Lunges: focus on using the glutes and the inner thigh to pull yourself back to the start. Again keeping the weight in heels on that planted foot.
