Day 1

how many sets for each exercise? Do you just go through everything once? or do you do a number of sets?

If you log into the members area, you'll see a link called "Download the Workouts for 12-18 Year Old Athletes (Week 1 - 12)". Click that link to download the workout PDF with all the information. It includes instructions and explains exactly how many reps, sets, etc for each day.

If you have any other questions, let us know. But once you find the PDF I think it will answer most of your questions.

BTW, here's the link to the members area:

I just bought the program and i cannot find the percentage of weight to do on stuff like bench and squats?

Every exercise should focus on technique first. DO NOT sacrifice your technique for more weight or more speed. Athletes who do this are setting themselves up to be unsuccessful in the long run. All of their hard work will not pay off for them and may actually hold them back from being successful.

Once you're able to perform the exercises with proper technique, you can start increasing the load for the strength training exercises. Weights and height of box /hurdles will vary depending upon strength level of the athlete.

Generally speaking, you should figure out how much weight you'll need to challenge yourself on the 2nd and 3rd set. So on your last one or two reps, you are close to failure but can still complete the rep. This takes experience and slowly adding weight.

Finally, as you follow the program, listen to your body. Your body may require more rest between workout days. If something doesn’t feel right, don’t continue with that exercise. Have it checked out by a trainer or a doctor.
