Summary: Video one is five stars, video two is three stars
Review: Video one begins on the floor with an intense ab routine followed by glutes. After doing the original basic series for 3 months, five times a week, I decided to try something else. I have done this video for three weeks now and it's still very difficult to get through the glutes section. However, I don't feel right if I don't do this ab routine. Other ab routines from other videos just don't give me the same benefits.Video two focuses more on the legs. One irritating thing is that he keeps saying in what I perceive as the hardest part of the workout that this is just the basic video. It's not very encouraging. I do like how Billy reminds you to focus and you'll get through it. I have damaged cartilage in my right knee from years of dancing, so I look for videos that are entertaining, mentally stimulating, but provide as little impact as possible. Video two strains my knee, so I have only done it five times and prefer video one, given visible improvements in my abdominals and posture after just three weeks.
