I've been working out 7 days a week for about a month now. Everyday I do at least an hour of cardio where my HR averages in the 150s and tops out at 170s.

I am experiencing some muscle soreness and/or knee soreness and was wondering if it is not advisable to exercise 7 days a week. It seems to me that some people here do and others do not. The soreness is very minor and usually is non-existant on days where I take it easy.

I don't think I can stop (at least not on a regular basis) since I really enjoy my routine but I am thinking of easing up a bit and lowering the intensity so I can continue at my current pace.

Everyone is different but I'm curious what folks here think about this topic?

What's your goals? Why do you feel you need to workout 7 days a week?
Heck even God took a day off after creating the world ;)

I'd suggest backing it off some, you're due for an overuse injury if you continue. I think 4-5 days on / 2-3 off is pretty sufficient if you're not a professional athlete. You shouldn't really be sore when you are working out... I find quite the opposite actually. I suspect, possibly, tendonitis. Exercise is addictive (and I don't mean that figuratively speaking, you can get addicted to the endorphin release "runner's high"). Learn to take it easy once in a while.

Not sure on the type of cardio you are doing but maybe switch up the exercise to something that impacts the knee less.....like speed walking, elliptical training, rowing, swimming, climbing, biking. Changing up cardio methods can be enjoyable and offer new challenges as well.

sf1977, listen to your body.

I don't see any problem working out 7 days a week (I've been doing so since January) but if you're starting to get real soreness, not just normal muscle DOMS, pay attention to it. If your joints are sore after cardio then RICE 'em (Rest, Ice Compression, Elevation). At the very least, get compression on 'em as soon as you're done with cardio to minimize any swelling.

Many people like to have a rest day in their workout program and advocate it for avoiding injury. I, like you, enjoy working out too much to really appreciate a day off. I make sure a couple of my cardio workout days are low-intensity and low-impact to give my joints and muscles some time to recover while still working my cardiovascular system.

I second Gordo's suggestion of mixing up the types of cardio you're doing. Getting some swimming in would be an excellent way to keep stress off of your joints a couple days a week while still getting a great cardio workout.

Hey you're exercising similar to me. So obviously I'm not going to tell you that it's bad.

One reason you have very little soreness is that you do that cardio. Your workout has given you a decent lactate threshold, and your VO2max is probably not bad either.

You can shift the type of cardio to something easier on your knee and keep on going if you want. What are you doing now? We can suggest lots of knee friendly work.

Thanks for the feedback guys,

Today I was thinking of taking a rest day but instead did a 'recovery' mild cardio program which consisted of cycling b/t 115 - 135 bpm for 45 minutes. I figured this would be a good compromise.

I do all my cardio by cycling. I think it would be okay to take a day off once or twice a week but right now I am not ready to slow down.
