This lower - body circuit is great for strengthening and toning your lower body and, considering some of the largest muscles of the body can be found in your
legs, you get the added bonus of
serious calorie
burn.
That's the key to achieving strong and sculpted
legs, as these movements (especially when performed with heavy weight) have been shown to increase growth hormone,
burn fat for up to 48 hours following your workout, build
serious muscle, and increase sports performance (1, 2, 3).
