Hey guys I'm soon thinking of joining a gridiron team, now what muscles do you reckon I should work the hardest?

Cos it all depends on what position I'm put at.

If I get MLB (Middle Line Backer) I gotta do tackles and intercept passes so would I need to work the hams/quads more to push through the people barrier, also upper body strengths?

If I get WR or TE (Wide Reciever, Tight End) I gotta do alot of long sprints down the field and change directions (posts) while catching the ball on the fly (I'm assuming calves would need to be worked for agility?) Although I'm only really good for sprints for a short amount of time, lung capacity sucks

If I get HB (Half Back) there's frequent short sprints and agility needed, also shoulder charges, dukes, stiff arms ect

Or even QB which I doubt but people always tell me I have a really strong and long precise throw with gridiron balls, The main focus would be power and the occasional agility dukes ect..

I used to play all these positions when we'd play at school and yeah going to join a team hopefully, what should I focus on strongly and what muscles would be worked most in general out of all of those positions put together?

Any help on it would be greatly appreciated

Any sport requires you to have muscle strength in all areas. If you start concentrating on isolating muscle areas, you end up with muscle imbalances, which can cause all sorts of problems. Just stick to building all your muscle groups, keeping up aerobic fitness, and whatever grid iron training you guys do as a team.

Obviously your training will have to be determined by the position you get. Wide receivers e.t.c require alot of sprint work, while half-back or line men require alot of power and strength over really short distances.

Stick to a general program for the time being, then modify it once you figure out where you'll be.

Your position decision is going to be largely impacted by body composition. Much of what decides your position is going to be height, weight, speed and muscular strength areas.

I've played gridiron for Gold Coast and from personal experience you'd be best to keep a general training program until the preseason.

How is the team training?

High intensity or what? Anything I could practice on in pre-season to help? e.g run posts..

Team training is good. A lot of drills. depending on how many people you're squad has you may need to be able to slot into one offensive and one defensive position. Since you're not sure what position you'll play, work on your 40 metre sprint times (crucial for wide recievers as well as both offensive and defensive backs) You'll also benefit from a higher level of core strength, so I'd look into training that. If you can find a nice balance of speed and strength you'll leave many doors open.

I'm going to the Northside Rhino's which funnily enough is at the gabba..

On average what would you say a 40 meter sprint time be for gridiron players?
Cos I know once I'm in the gear it may be a bit harder to run in with the helmet ect, so I wanna be prepared for it and all.

As others have said keep training all muscle groups and once you have your position decide the primary muscle to excel at that position and incorporate how these muscles are used into your weights routine. ie. if you need agile, fast contracting calves, when doing calf exercises increase the speed that you push with your calves, but continue to move slowly on the negative part of the exercise.
