yeah, well once you get in a routine with it you will most likely only feel bad on the days you are taking a break. That first month will be hard forsure. I remember how much pain I would be in if I stopped training for a few days. Way more then when I did...except for that first month. I remember this time when I had flown to LA from Hawaii and was staying at my homegirls house. I woke up around 3:30 am and grabbed my gloves, jump rope and was walking in my socks to the front door to get my shoes and all of a sudden I hear this sound in the direction of the cold tile beneath my feet.. I had not trained in about 3 days and started feeling my muscles begin to tighten up but wasn't really trippin... until I hear this sound. I think back and it sounded like styrofoam ripping or more like the sound a t-shirt makes if you rip it apart. It was my calf! From walking across the tile of all things! It is even possible that the noise I heard was only in my head but it seemed so loud! I did not make it to the gym that day... it took weeks for that to get better.
