|Hi, I'm a 15 year old and I would like a training program to follow this summer just to get my personal fitness up. At school we do stuff like 12 minute run, pushup/situp test, chinup test, how long you can hold yourself on a bar, vertical leap that kind of stuff. This year I was getting mostly 4/5 on the tests some 5/5 but I would like to be dominating these tests next year, so does anyone have a guide I can follow for this summer something simple peferrably that i could do at home. I know that this might sound dumb because I could just do all these exercises and try to improve on them but I want something that's organized and keeps me motivated. Also I'm reading all this stuff about like how running too much makes you lose your quickness, or doing too many situps is bad for your back so I just wanted to be safe. Anyways if anyone has a guide for me thats safe for teens and easy to follow I'd greatly appreciate it.
