Re: good youtube workouts?
On days that I don't feel like going to the gym(like today), the 'BeFit' channel on youtube is my everything. They have a lot of different workouts(including Jillian Michaels stuff)

Also, 'ToneItUp'

If I didn't enjoy flirting at the gym so much(and the social interaction), I'd probably cancel my membership. The internet has all the workouts you need.
