I read this somewhere, can't recall where, but hey ho. It made me think about things. Sore today, strong tomorrow. I take that to mean my burning thighs and achy arms. I mean seriously, every muscle is aching so much.
However, taking this in mind, that means that I am sore today (and possibly for several days after today if I'm honest) but I will be strong tomorrow ( or maybe in a few weeks at any rate!).
I think the point is that putting the effort in now will pay dividends in the future. So even when my legs burn and every muscle is on fire, months from now, I will look fabulous, and the pain and effort will be worth it.
It means knuckle down and work at it. I am inspired :)
