I am from NJ. I am still not familiar with the 6-day cycle. In MLB, it's more common with 6-day cycle.
We went to swim after our morning workout yesterday. I just realized that aquatic exercise is another great way to relax and build muscles as well. It's actually an legitimate practice for many athletes in various sports. It often is used in rehab process. Thus, many athletes used sauna or hot tub after the game.
My son pitched 110+ innings from April, 2016-July, 2015 with 87 K and 0.75 ERA. I realized that exceeded the physical strain for a 13YO. I forced him NOT to play fall ball and ran Cross Country to build his lower body.
Unfortunately, he sprained his UCL this past April while goofing off. He has rested since then and just came back to pitch recently. He helped his MS team to win the 4th straight county championship by pitching 5 2/3 innings to a good batting team.
We hope he will have a great summer season, but he is taking his time to re-train his mechanics and timing. Our goal is to enjoy the game and the experience until he decides he has enough.
So, go out and have fun, kids! Build strong fundamentals and Don't Rush!!!! There is never a short cut!!!!!
