| Arms get tired when running
Hi all,
I am new to running, and recently started doing short bursts (5 minutes) as part of a circuit that my trainer put me on. Lately, as I am increasing my speed little by little, I am noticing that my arms get tired and sometimes even cramp up! What it does is distract me from how good the rest of me feels and makes me feel tired and frustrated.
Any idea why this might be happening or how to fix it?
Any advice would be gratly appreciated! Thanks. |
