I just turned 15 yesterday and I seem to be in a pickle. I weigh currently 178 and I am 5 '10'. I am currently going to try and play outside linebacker or even a Defensive End. I have been taking C4 cellucore Pre-Workout, with Amino Energy mid workout, followed by Gold Standard Whey protein. I am looking for someone to recommend a plan of what I should do concerning workouts and or what other supplements I should take instead. I am a Freshman who next year will be a sophmore who is looking to start JV. Thanks!
First, you do not need all of those supplements. A sound diet(ie. getting your vitamins,minerals,and veggies) and a protein shake here or there(I recommend the EAS Complete) will be enough to see strength gains.
If you are not strength training I suggest you start. 2 to 3 days a week. There are a ton of different programs out there, just find one and do it. Also be sure to do endurance cardio as well as power cardio(sprints). Cardio will help you maintain a high level of exertion for longer period of time
Finally, position drills and skills training are super valuable in football. Footwork drills like this(https://youtu.be/6SiDrfWbMIo) you can do on your own and will help with agility. Yes these are DB drills but quick feet and acceleration help all positions. For OLB the "W" style drills are perfect.
