Re: "Athletic Training"
If you can find a sport specific facility for yur sport then the anseer is yes.
Coming from a franchise sport facility as a coach and director I can see the improvements of various equipment.
For cost effectiveness: ladders, reaction balls, mini hurdles, harness, cones.
If you had the means: slideboards, oly. weights, indoor facility for sport specific.
Stability ball exercises can work a lot of balance and core strength.
And i just came back from Vegas, those actors at Le Reve have extreme core strength. Nothing to joke about those guys and girls.
