Since I can not do any impact yet, I am into my third week rotation with 30 min on that bike(which I hate, Cathes workouts are much more fun) and then doing CTX upper body. I think my hips are getting toned. I thought with all the sitting only my quads would get the benefits. Is this wishful thinking on my hips or will the bike tone that? It might make it easier doing it if I see results. Maybe its the increase in cardio? My glutes just seem to get tired of sitting and its a long 30 min. Thanks
