Thanks for LOTS of good advice!
I had not read your post before commiting to run a 400m today! haha.. I'll try and not run it at quite 100% so I don't end up with a groin strain or something silly
I was never a great athlete, but I have lost weight doing cardio before (cycling and trekking). I do enjoy long work outs in zone2 and 3 (and even the pain in zone 4)
Right now, I don't really have a choice with increasing activity while dieting, as pretty much all mileage is currently "increasing mileage", but I see your point. cheers!
As mentioned, the bulk of the cardio is so far rowing as to not strain my body too much. I haven't invested in a garmin yet, but I'm conscious of not training too hard. That's fairly easy on the rowing machine.
Other than a rowing machine, I also own a spinning bike and a racer bike.. (Although I don't fit my biking clothes! haha!)
So I THINK I have the neccecary options for enough cardio training without pounding my legs to death under control for now, but we'll see.. There's been minimum amount of running so far, so I am very curious as to how my body (especially my left knee) will handle many miles of running.
The "hard" work outs so far has pretty much been the uphill walking (That round of mine starts with an about 1 mile 350-400 feet hill and the treks with rucksacks starts with with over 1500 feet elevation of climbing)
Have to admit though, just from running my round yesterday I do feel it ever so slightly in my left knee which is probably why I wrote that post in the first place yesterday..
