Here on the Tom’s Guide fitness desk, we love nothing more than a weird workout challenge. Looking for some inspiration, I stumbled across Sweat app CEO and trainer Kayla Itsines’ 90-rep squat challenge. Squats are an excellent exercise when it comes to working the gluteus maximus, medius, and minimus, the quads, hamstrings, hip flexors, calves, and core. You can do squats using just your body weight, or up the intensity by adding one of the best resistance bands, or best adjustable dumbbells.
I often use squats as part of my workout routine, so decided to use Kayla Itsines’ 90-rep squat challenge as a workout finisher. The objective is to move as quickly as possible, while maintaining good form, and record your time as a marker of your fitness. The entire workout took me less than five minutes but reminded me how versatile the humble squat is when it comes to targeting different muscles in your lower body.
