I’m training my sons for their various sports and I see all these gimmicks in performance training: pulling a tire, pulling a parachute, running away from your trainer with a resistance band around your waist, etc.
I was a 800m in college and we didn’t do anything besides run and lift, but that was 25 years ago.
So whats the current expertise in sports science: are there any “gimmicks” that actually work, or am I better off with having the boys do good old fashioned sprints, hills, etc?
Thanks
