As many throwers are quite heavily built, it is often a lot
of strain on their joints to do a lot of running to get the base fitness. Therefore,
whilst some is good, we wouldn't suggest too much, instead some other forms
of aerobic cross training can be good such as cycling, swimming or rowing, which
involve less stress on joints.
Also circuits training will help with general fitness and some core stability,
although again, high impact exercises such as squat jumps may be avoided, if you
are prone to problems with your knees for example.
