In your thread last week ( http://tnation.T-Nation.com/free_online_forum/sports_body_training_performance_bodybuilding_beginner/new_guy_workout_routine ), you said:
With that in mind, you might want to ditch the homemade plan and go with Joe DeFranco's Westside for Skinny Bastards 2:
It's three days of lifting and three days of running drills that are, as DeFranco explains, "geared toward football players who are preparing for training camp." I'm sure it'd carryover to your situation. Just a suggestion. Or consider the following...
That look like 75% of most commercial gym lifters' "bodybuilding workouts", not like something a lacrosse player trying to improve his sport needs to be doing right now. First, the set/rep scheme isn't on track. 5x5 is solid, sure, but you could use a little more variety where everything isn't "just" 5x5 or 3x8 (but that really ties into the overall program, split, and weekly frequency).
You're giving your biceps almost as much attention as you're giving your entire legs. That's just nutty. Also, I doubt you're able to push yourself as much as possible on those 5x5 deadlifts right after squatting 5x5, especially if you're just getting back into doing deads. If you're going to do those two lifts in the same session, go heavier/lower rep on one and relatively-lighter/higher rep with the other, and consider alternating which is which each week.
The shoulder workout is wonky, because you're really not gaining much by having two presses in the same workout. The triceps workout is disorganized; I'd choose just one compound exercise and maybe one isolation exercise (same idea with biceps, just one or two exercises necessary).
So yeah, sorry to whiz on your parade, but I don't dig this plan for your current goals.
What happens after day 4, the cycle starts right over? If so, that's kinda crazy and way overboard on the frequency and volume. For now, I'd look to lift three or four days a week, tops.
If "strength and athleticism" are the goal, I'd want to use less of a bodypart split and something more like and upper/lower split to build (cover your eyes, bodybuilders) more functional strength and muscle.
Like what? Weighted ab work? Crunch variations? Anti-rotation work (like Tony Gentilcore and Nick Tumminello have spoken much about)? Just sayin', you wouldn't comment "I'm probably going to throw in a little hamstring work each day." Especially in your sport, the entire core (not just "abs") deserves as much attention as any other muscle.
I'd use power cleans as the first or second exercise on an upper body day (or on what you currently have as either back or shoulder day).
I'd either order one from Elitefts.com or just check your local sporting goods stores. What kind of weight are you doing for dips right now?
