Squats are one of the best exercises out there when it comes to building strength in the legs. With lots of variations on the classic lower-body exercise to keep things interesting, there are many benefits of squats and you can use them to develop muscle in your quads, glutes, calves, and hamstrings.
I regularly incorporate squats into my lower-body workouts, so when I noticed that personal trainer and Sweat app founder Kayla Itsines had posted a squat challenge on her Instagram page, I knew I had to give it a go.
