I need to increase my Stride but, i also
know if you stretch to far you can throw
off your center alignment. With would
cause you to lose power in your steps.
First,
Check the threads on the old forum under Biomechanics. You can find a wealth of information there.
I dont remember the thread being discussed recently, but this question is similar to one posted a few days ago. Stride is variable to athlete and can be affected by weakness, tightness, pressing, etc.
It seems a cliche, but can you link a video of your sprints, so we can make better judgements? thanks
