The Human Trainer customer service was outstanding! I spoke to a gentleman in customer service and I will only use his initials here as MP, who was very courteous and gave a wonderful shopping experience. if only I had the money, I would surely buy another trainer, because my husband and I are competing to use this one. Like I said before, it is very sturdy and user friendly. I highly recommend the HT suspension trainer. The workout DVD takes you through many different exercises at different levels (beginners, intermediate and advance) at 7 min each. Then there are four separate 4 min sessions to work on different body parts. The workout on the DVD is very good. I just want to note the I only watched the workout DVD once because I have had the trainer over a week. There is a narrator guiding you along on the DVD and at the corner of your TV screen you will get to preview the next workout you will be doing so you can prepare for the change. I also like the music that goes along with the workout. It's worth every cent.
