I've been lifting for a year inconsistently but made ideal gains throughout. However now I am basically back to being a beginner since I haven't lifted in about 3-4 months.I did this purposely because I had gained too much mass (bulked up the wrong way) and became way too slow for basketball and because I've been plagued with injury. I've also been inactive with basketball and track so I have lost a a lot of my athletic ability. (One example is that I went from a 28inch vertical to an 18inch vertical)
So now I'm basically starting from scratch. My main goals are to increase my athleticism, strength, speed, agility, and endurance (for both my muscles and heart). As of today I am 5'10, 155lbs (was 172 before I stopped lifting) and I wish to stay around the 155-175 mark so I don't get to slow for basketball and track (sprints).
Once again I am not looking to get huge, but to make myself a sufficient athlete(track sprinter, basketball).
1a) My question is where do I start and how do I start?
2a) Build a strong core and flexibility base before jumping into a routine?
b) Are there any books that I can order which can give me more knowledge on how to construct a proper diet orientated towards my athletic goals?
c) How should I go about increasing the following: (Strength, speed, agility, vertical, etc) - What routines should I start with since I am beginning again.
d) How should I construct my routines? Any books or sites?
Yes I know the questions are broad, I just need some feedback on where to start =/
