For this football offseason I am really lifting hard and doing all the core stuff and cleans(I know this helps speed too) and know what I am doing as far as that goes. So I feel like I have the strength and size part covered. But I really feel like I need to work on speed, agility, and explosiveness/power. I am not sure what to do as far as that goes, but I feel like I have some options and was wondering what you guys thought of them.
1. Get this book which seems to have great reviews and might help: http://www.amazon.com/Complete-Condi.../dp/0880115211
2. Go to this place I found that is close to me. Not sure how good they are as I dont know much about it, so I'll let you guys take a look at it. It seems pricey but I don't know. http://www.davisspeedcenter.com/
3. Maybe I should just do my own stuff, but not exactly sure where I would do it and what to do. If you guys recommend this could you help me out a lot with that cuz I would need it. So what type of power/speed stuff is good for football (I know sprinting and plyos, but I dont have plyo equipment and stuff and it seems like I should do more than just sprints to really improve).
I really want to work hard this offseason because I have a chance to start and defensive end this year and its my last chance as a senior.
So what do you guys suggest I do? Thanks for the Help.....
