Here is a great workout to get your booty, thighs and legs in shape in a very short time. Tabata Squats with weights. I would not recommend it to everyone. Make sure your body is  a little stronger. In other words you should know what you are doing, and how to keep a good form without thinking about it.  That will develop naturally when you do some workouts before attempting this one. Also, make sure to warm up and stretch before. Tabata is a fantastic addition to your workout routine and finalize your  exercising for a day 🙂  Have fun!
