Big time likes on this. Magnesium is really good for leg muscles. Also, if you have ever experienced restless leg type syndrome, it really helps. We are on ladders and roofs all day, so some days the legs are like jelly at the end of the day. We don't pressure wash or do windows anymore. Just roof cleaning and gutter clean outs every day, so we do a LOT of ladder climbing.
On really busy days, I will generally grab a bottle of the Muscle Milk at the end of the day. It really helps to relax and recoup the legs and arms. I am not a weight lifter or anything like that, but I do know that the Milk was designed to help recover after workouts, and that is pretty much sums up what all of us do every day.
You WFP guys have my undying respect. That is one heck of a daily workout. My WFP gear is in the corner of the garage. I use it on my house.
I also drink Gatorade during the day. I don't like drinking too much because it is way too much sugar and other stuff. I take a bottle and dump about a 1/4 in a water bottle and fill the rest with water. That way I am still getting some of the electrolytes and other stuff in the Gatorade. I go through a quart of Gatorade on a good day mixing 5 or 6 bottles of water/gatorade mix.
