I've been feeling pretty tired lately and it seems like I need a good recharge. I play tennis 5 times a week, about 2-3 hours each time. I do cardio everyday for at least 45 minutes. I just got off from another month of HIIT, where I did it 3 times per week. I go to my local 24hours fitness and lift weights as well as attending the yoga class 4 times a week. I am about to start on p90x. So, I've pretty much decided that I'd take a complete break, from EVERYTHING for an entire week before I start the p90x program. Is this a good idea? I do feel a lot of fatigue lately and even a good 9 hours sleep doesn't help me recover completely. My muscles are tired, at least one muscle group is always sore. Is a week off too long/too short? I will of course be eating extra healthy on the break as well. I probably will also be stretching everyday still, but other then that, I'll just be laying down or sitting on my ass.
