So - you’re going to learn to run fast by hardly running at all??
Football - requires pretty much only Acc work, little to no top speed work and No Speed Endurance.
But you also have to be on your feet for a long time, doing stop start tempo type running.
If you’re spending all this time doing weights just to get Strong - you’ll do well for the first say Quarter of the game - then the “weaker” guys who follow a much more Concurrent training plan will run rings around you in the last 3/4 of the game.
You’re not training for say Shot Put - 1-3 blasts as hard as you can, game over.
