So please look after your knees, I wince when I see people running with bandages on their knees, if the knee hurts, there's a reason, don't make it worse.
Goodness, I so agree.
No point in flogging yourself through a punishing exercise regime only to store up injury problems in the future.
We all think we are indestructible, don't we? plus the whole 'no pain no gain' idea.
Thankfully almost all of us learn better, in time. Although usually not until we have some damage to show for it.
