When it comes to sprinting I have never used my arms like I should; they just kind of hung there.
In the past two years I have increased my upper body strength considerably and I don’t know if it’s the strength or just the awareness that i need to USE my arms but I make sure I use them!
I mean, when I do the 30m sprints I slam my arms up and down and I “feel” like I’m generating more power! Anyhow, is it true that the faster I pump my arms the faster I should theoretically be able to run?
