Looking to tone your lower body? Then you definitely need to try this video from Lifeskool. I'll warn you ahead of time, it's hard. Not only is it heavy in lunges and squats, and when I say heavy I mean the entire workout is basically lunges and squats, it's also pretty fast paced and nonstop. One thing is for sure though, you're definitely going to feel the burn. Just don't curse my name when you can't sit on the toilet in two days.
Fit's Tip: If you've never done a lunge or squat in your life, or if you have bad knees, you may want to opt out until your lower body is stronger.
