Gone Fishin’!

I played football for the first time in my life last season. I was on the JV team. This year i am moving up to the varsity team. I played defensive tackle, but im not strong enough.I didnt start and i dont think i will start this year. but i would love to start in grade 12. How can i get stronger hit harder and tackle better. What are some good stratagies to a good tackle and harder hit.

run hills and you will get stronger
