Triometrics Post Workout Wrap-Up: Okay, for the first 17 minutes I was thinking, "this is great! Trio is hard for me but when you work up to it in a minute format (20 sec easy, 20 sec moderate, 20 sec trio) I could do it! However, once the 12 minute mark came up I quickly changed my tune... Hard to where I gave up? Almost....but NO WAY! I did what I could, struggling with balance A LOT, and I am looking forward to the next time I do it being all that better! For me, this has been the most difficult X3 workout yet. Final thought...ONCE AGAIN, it amazes me that this is a "Leg Workout" where I sweat and work the core/balance all in 30 minutes! BRILLIANT!
