I have had my Rip Trainer for a month now. VT_Rip provides me with the necessary tools to work out effectively. The timers are great. You can choose from Standard, Tabata, HIIT and Circle. The HD quality is stunning. At the end of my 30s - 10s x 4 workout, I'm soaked. The app is easy to use and the tracking system can keep you motivated. I have 3 suggstions: a. Include a quick audio review of the proper technique with demos. b. Include use of TRX's safety strap. c. By merging this app with, say, the VT_Suspension Trainer and VT_Kettlebell Trainer y ou could then create a super fusion VT workout that would blow away anythig on the market. Keep up the great work. I look forward to seeing more, creative exercises added in the future. Cheers, Anthony
