Friday Squat Circuits

Switching up my weekly lifting routine a bit, today is my first Friday were I squat. On Monday's I'll be Front Squatting and Friday's will be regular Squats. Still on the 'lean routine' I'm dropping the weight on my sets, trying to keep moving and keep the heart rate up throught the entire routine. Here's today's...
