It’s unreasonable to go sprint 100% all out when you haven’t in a while.
Sprinting all out after a layoff is something of a no no.
Tight and/or weak hamstrings combined with the all out dash are what hamstring pulls are made of.
There is a reasonable way however, a way berift of such potential issues. This is how you start off when you get back into sprinting.
If you haven’t sprinted in a long while, are a big guy, an older guy, or some combination of these here’s what you do :
Flying 40s
Flying 40s are a drill I ripped out of some college football programs off season workout program.
You start at an endzone, and slowly run/jog 30 yards. Now you kick into gear for 40 yards. Many will controlled sprint this when coming in from a layoff. Use your head. I find it unlikely to run at 100% when it’s been a while. It takes a little time to relearn proper sprint mechanics. You jog out the last 30, and are now at the opposite endzone.
Now like my wrestling prep during preseason nights, I’m not on a football field. I use the street, it doesn’t have to be the exact distances, it’s the ease-controlled or all out-ease principle behind the drill.
When you start sprinting after a layoff use the principle of the flying 40.
Also use a slight incline if possible. This makes it even safer.
Go forth and sprint. It feels amazing.
