Colleges are all different. Some workouts are really hard, others are relatively easy. I know a couple colleges that used the P90X workouts. I advise you to make your own workout and learn as much as you can about the proper way to lift for baseball. I can try and help you make a workout if you want.
My college had a lot of reps and worked muscles that were unnecessary for baseball. So just because it is a college workout does not mean it helps you as much as another workout could. So again, you should make a workout that challenges you and prepares you for the college season. It's better to be over prepared than underprepared.
