I think it was 3 weeks ago I suffered a minor hamstring injury while doing cardio. It seemed to have settled itself after a few days and after immediately applying cold compresses every 10 minutes.  8ugger me but it happened again today almost at the end of my cardio.  Got the power walking up to 6.7 (whatever that really is in kphs? but it was FAST) and then BANG.  I felt it that time! Same hamstring. So here am I back home after only 45 minutes WO and swathed in cold compresses again. Must remember to take it off after 10 minutes. Looks like Im doing only arm and chest exercises for some time to come now. Juts as well I've got well developed legs.  Well they had to be to support the 19 stone I used to be!

Keep your chin up.. its a bugger, are you doing any light stretches or anything before you do your
cardio.????

Jon i'm not being funny but you should have rested it for longer and certainly shouldnt have been power walking at a fast pace, i found my hamstring took quite a while to repair so take it easy mate

Thanks Kez, I now know I've been too adventurous. I thought just because it had stopped hurting that it was OK. It was OK for about a week at slower walking speeds, but when I upped the rate of knots it showed its weakness. Well I've certainly learned a lesson! And Jo, to be honest I haven't been doing  any stretches as up till now I didn't think I needed them'''another lesson!   I always start the cardio at a slow speed and then gradually increase it. Who says you're never too old to learn eh?
So now not only do I take more days rest than I used to but without cardio I'll just have to concentrate on arms, back and chest,....... but with plenty of rest in between. Thanks guys and gals for all the support and great advice. I mean that.

Ive downloaded the followjg from WIKAPAEDIA.

Quoted Text

The immediate treatment of any muscle injury consists of the RICE protocol - rest, ice,compression, and elevation[1] (never apply ice directly to the skin). This is aimed at reducing the bleeding and damage within the muscle tissue. Resting may be the common sense approach, but it is one that is often ignored by competitive athletes. This is unwise, since it does not take much to turn a grade one strain into a grade two, or a grade two strain into a grade three. As a general rule, grade one hamstring strains should be rested from sporting activity for about 3 weeks and grade two injuries for about 4 to 6 weeks.

I've not been very sensible have I?

How is the hamstring  

Hi Jo, just returned from gym. Instructor suggested I try slowwwwwwwww cardio on the treadmill at about 4 to 4.5 kph.  Did 2 session of 10 minutes and no problems; I can slowly increase the speed over the next couple of weeks.
Had 2 days rest and I found that I'm lifting better, as I expected.
Managed to re-built the PC but lost many programs although I backuped a lot on an external IOMEGA. New machine is MUCH faster with 2 core AMD processor and 2gb memory plus new graphics card.
Jo, hows the toothache?
