I can see that by slight modification to some of the training regimes I currently do, I can strengthen many presently weaker areas of mine to become a competitor.

In the gym, what weight training devices and/or free weights would work for me?

For instance: Caber toss, Would I use a strenous workout regime on the rowing/leg press/chinups/etc.?

I realize that there is no substitute for a caber that will give me the practice of actually throwing the caber. But, the muscle groups can be strengthened and therefore afford me a better turn at losing my balance when it's my turn to flip the caber over! :rolleyes:

The weights:
Stone 16lb - thrown like a shot put
Heavy Weight for distance 56lb (over 40yo. for me 42lb)
Light weight for distance 28lb
Heavy Hammer 22lb (over 40yo. for me 16lb)
Caber 16 - 22ft long 90 - 150 lbs
Sheaf toss 16-20lb bag - thrown for height
Heavy weight for height - 56lb (over 40yo. for me 42lb)

Men over 40 - Masters (But you can still compete with the Ams if you choose)
Same except that the Heavy weight is 42lb instead of 56lb and you throw the light hammer 16lb instead of the 22lb. Generally you throw a smaller caber too.
