Absolutely. IMO one should do what's interests them and doesn't cause injury and over-training. The goal is to get healthy, not to wreck one's life. Again, just in my humble, the valuable part of cross-fit is how it strings exercise together, the selection of movements and rep ranges, how it shifts focus and alleviates workout boredom. Scaling down is a perfectly good concept and you can get all the benefits of working out 3 days on/ 1 off with a great variety and challenging moves. I simply look up how many rounds the elite cross-fitters posted for each day and repeat the average of their reps. Usually takes me about 2-3 times longer, but I am not claiming to be an athlete of any degree. Just someone who likes keeping as fit as she can be. Better gifted people would get kicks from competing at the goal level. I am perfectly fine with calling it Leida's Workout, not Cross-Fit.Do you know what intensity they're meant to be done at? Obviously if you decrease the intensity enough and remove time constraints, recovery will not be an issue. I can run marathons almost daily without recovery issues because I scale them down to 2.62 miles.
