So I forget when I started, but initially I was doing the 6 on, 1 off, and kicking ass. I have definitely seen results, but it's been 3 months since I got it, and due to my schedule I only get Thursday and Friday nights now where I can work out. So I've been in phase 1 mode to just maintain the progress made, which has been working.
I expect to start phase 2 in December when I have the small winter break from school so I can do 6 on 1 off again, or at least more than 2. The hanging out with the girlfriend on weekends will eat up 1 day for sure, but at least 5 days on is possible.
I'm in the same shape if not better than back in high school though just with phase 1 work outs.
Best money I ever spent.
