I am wanting to take advantage of the Spring Sale without breaking the bank. I did Cathe workouts for years, but then drifted away to focus on triathlons. I now have a weird condition that makes it really difficult for me to run, although I have no physical limitations. Once I acknowledged that running was out, I pulled out my relatively unused LIS series. I am following the rotation and really enjoying it. Now I am trying to figure out what will be next. I think I am most interested in ICE, Strong & Sweaty, and XTrain. If I am only getting 2 which ones should I get? In terms of goals, basically I want to stay fit and injury free.
