I really hope Cathe's people are paying attention to all this. She's known for doing tough cardio and her tough cardio fans love her for it and don't want her easing up one bit. But nearly all of us are dealing with physical limitations (mostly knees, ankles, and back... I've noticed) at least one day per week. I've often felt Cathe could create cardio workouts that essentially address two separate audiences: 1) The hardcore life-long Catheites who want Cathe to continue making the toughest cardio workouts on the market and 2) The ever-growing crowds who want the most challenging cardio workout possible, without doing further damage to their joints. All her cardio routines could be dual-releases, with 2 new workouts, each catering to those two specific groups, so everyone gets what they want from the only person who isn't going to give modifiers a stupid twinkie workout a four-year old could do. Or, better, she could put two workouts on each cardio release so you could choose. That way, you could usually do the all-out workout unless you're knees are aching a bit, in which case you could do the other. Laugh if you will, but none of us are getting any younger, nearly everyone has some kind of issue or will, at some point. I'm telling you, it's a growth industry and nobody else is thinking about this. Like I said, our knees may be a bit swollen but our hearts can take it and we don't need no twinkie workouts!
