What are some non-swimming exercises I can do to help prepare for the swim team?

do abs and cardio. run in the morning and then after you get back do some crunches and planks

running or lifting weight can prepare you for the swim season

You can do stuff like: run, ride a bike, jump rope, jumping jacks, push ups, sit ups, V ups, lunges, squats, squat jumps, side taps, etc. Dry land: 50 crunches center 10 push ups regular 50 crunches right 10 push ups hands under chest 50 crunches left 10 push ups hands inward 50 crunches knees at a 90 angle 10 push ups diamond 50 crunches legs perpendicular (straight up) 10 push ups knuckles 50 crunches bicycle 10 push ups arms wider than shoulder width apart 50 crunches choice 10 push ups choice 25 V ups 25 lunges :30sec-1min 6 inches :30sec-1min plank 50 jumping jacks 25 stairs :30sec-1min squats 15 squat jumps http://sportsmedicine.about.com/od/tipsa%E2%80%A6

I would put together a dry land training schedule that works for you. Try a series of crunches, leg lifts, push ups, squat jumps, and scissor kicks. Exercises like that will definitely help you prepare for your high school swim team. Make sure to stretch before and after you do these exercises!

Any cardio, such as running would be good. I would also recommend some strength training of all muscle groups.
