how many days a week do you work out?

I started with 6 days a week with Sundays off but the past two weeks I've felt the urge to run on Sundays. So I guess I'm a 7 days a week person now.

6 days a week

I’m training for a half-marathon so I’m walking/running 5 days a week. I work with a trainer twice a week. If I’m in a recovery week, I’ll go to the gym on Sunday otherwise my long run on Saturday (13+ miles) is enough for the weekend.

Daily. Unless 'something' gets really sore and I fear there is damage, then I'll take a day off even though I don't want to. If I do that I usually heal up and have an even better workout the next time. Sometimes I just change the type of exercise to give certain muscles a break.
Change it up and you'll figure out what works for you, with your schedule, time. etc. After all , it's all about YOU.
Good luck!

I workout 5 days at week for an hour each session. 45 minutes of cardio and 15 minutes of circuit training/toning.

I don't like the term "working out" b/c people get cardio and lifting weights confused and improperly defined. You can do cardio 7 days a week with no problems. Your nutrition needs are different on a cardio day than a resistance day. You can do cardio on an empty stomach b/c your body uses fatty acids primarily for energy. Carbs and Protein are needed for muscular energy and strength. You shouldn't lift weights more than 4 days a week. Not that anyone on MFP is trying to be a competitor, but look around your gym. You never see serious or professional lifters working the same muscle group more than once a week. The process of lifting weights and enjoying the 24 hour a day fat burning cycle as a result from it requires lots of rest for the muscles you work. Primary and secondary movers need a week to recover. In the bigger picture, this is one of the major failures in our medical society to combat obesity and diabetes. We see and hear everywhere that we should "workout" or "exercise", but noone defines what that really is. When most people hear those buzz words they head to the local park or walk around the block. That's great...for the heart. But doesn't give the muscles the needed resistance in order for them to open their insulin receptors and uptake glucose when it's present. Cardio by itself isn't going to create the needed tears in our muscle tissue that our body uses fat and protein to repair around the clock. By 30 years old I was pre-diabetic, stroke candidate with my cholesterol 450+ and over 100 lbs overweight. Once I found the link to working out smarter and not harder as well as proper nutrition, I removed the weight and all of the health risks. And I only hit the weights for 30 minutes / 3 days a week and did @ 20 min of cardio twice a day.

6-7

5-7 days per week, usually at least 45 minute sessions (both cardio & weights)

Don't let TOM stop you! It may sound silly but in many cases, keeping up with your exercise routine will actually help with your energy and other symptoms.

5-6 days a week

2 days I take a class
2 days I do a workout DVD
1-2 days I'll do the treadmill

I work out six days a week. I take Sundays off (although sometimes I'll go for a short jog or something light). I'd probably still be alright if I worked out a bit less, but I absolutely won't go below four days a week unless there are extenuating circumstances.

It all depends on your goals and the amount of time you can feasibly work out, really. If your goal is simply fat loss and you've got a busy schedule I think four days a week is plenty.

I average 5 days a week. Sometimes 4, sometimes 6, but normally 5.

Strength training monday - friday and cardio monday-saturday giving myself Sunday off to either just spend time with family or do some cardio if I feel like it. I try not to kill myself and make sure I am focused and ready to step on the scale monday at 10:30

I think it's fine....I've never worked 7/d wk.
