I want to start doing strength training for two purposes: Injury prevention and Power/Stability. What kind of reps should I be looking for to prevent injury? Just your basic 10 reps 3 sets? The predicament here is that training for power involves 1 - 5 reps, so they kind of cross wires. Now for the power training: Do I have to be in the gym for this? I don't have enough money to be paying for a personal trainer to spot me while I'm lifting massive ammounts of weight. Plus it just seems like a hassel to have 3 spots around me while I'm trying to squat up an Olympic barbell for 3 reps. Can I just do plymotetrics? Or do I really want to be reaping the benefits of heavy lifting/power training. Also, I want to place a high emphasis on core work. What kind of exercises/reps do I want to increase my stability around my core: To fend of challenges, keeping stable while a 6'4 centre-half is jostling me for the ball. I have a build like David Silva, Iniesta etc. and my game doesn't evolve around supreme athleticism, just quick feet, acceleration and agility. And of course, my brain.
