3. Squats
A popular lower body strengthener, squats are a versatile way to burn out your muscles. Beyond working the glutes and the legs, it can get your heartbeat up and act as a form of daily cardio for 10-20 minutes. You can do a sumo squat, in which your legs are wider than your hips if you suffer from knee issues. Experiment with narrowing or widening your stance and consider adding a pulse or static hold. To add a challenge, you can also put a resistance band around your thighs.
