I went from not really working out at all (had gotten out of it) and I committed to three times every week. I'll be the first to admit that level one kicked my butt, and I knew that if I tried to force myself to do it every day I'd get burned out and just give up. On days between the shred I'd do extra cardio to help increase my endurance.
I thought level two was really difficult so I basically did that one for like 15 days... I just started 3 and it's not nearly as hard as I thought it would be.
It's taken me a while but my endurance has really improved. Committing to do this video for 20 minutes helped me get back into working out 5-6 times/week. I went from barely being able to get through the pushups in level one (had to do them on my knees) to being able to crank out man push ups! I've also lost about 15 pounds since I started it!
Good luck ladies.
