Lately my training has been less than great. Since I'm going to the HKC I've recently decided to revisit ETK and really contentrate on my form. I'm doing the ROP portion, not the program min. During the C&P Ladders I feel good(maybe a little winded because I like to minimize my rest periods), but during swings i lose my "zip". I'm only exercising 3 days so what happened to my energy? Sometimes after I'm done i get the cold chills and end up going to bed at 8:30 or so. In addition my joints have been achy and I'm just not as ready to go as I used to be. I feel WEAK! Any thoughts? Do I need to take some time off or possibly see the Doc?
