Will my heart explode?

When I jog, my heart rate goes to 195 beats per minute. Is that bad? I've recently started jogging, following the couch to 5k program. I've led a moderately active life thus far, but I've never been an athlete and I'm about 30 lbs overweight. I bought a heart rate monitor and wore it during my last run. I was surprised to see some very high numbers on the monitor. My resting heart rate (HR) is 65. I thought my max was 185. Brisk walking brought my heart up to about 140, and when I started to jog (slowly!) the monitor hit 195! I can jog for about three minutes at that level before I have to walk again.

I'm definitely huffing and puffing and sweating and red in the face at that level, but I don't feel like I'm going to barf or die. Now, here's my question: According to the materials that came with my monitor, I should be training in the 65-85% zone. Does this mean I can't run at this fitness level and should just be walking? Am I harming myself in some way by pushing my body and heart too hard during exercise? How long will it typically take for my heart to adjust to the strain of running and slow down a bit? Tips, thoughts, experiences all welcome. Thanks!

Too heavy for Couch to 5k?

I just had a doctor tell me I'm too heavy to run the Couch to 5k program. Is this really true? I'm 25/F, 5'6, 240 lbs with a sedentary job and no exercise routine to speak of for the past 6 years. About 3 weeks ago, I decided I was fed up and I started the Couch to 5k program at home on a treadmill. I made it through week 3 feeling great, still motivated and really enjoying the challenge. I was also doing lighter walk/runs and weights on the in between days of the program.

In order to work out with a friend, I started running outside at the track. Within 2 workouts running outdoors, I started having crippling pain in my knees. Worried I'd injured myself, I went to an osteopathic doctor. She told me that I was "100 lbs too heavy to be running" and that it was an unacceptable form of exercise for me. She said that "all the extra weight had pounded my knees into a severe sprain." She told me to stop eating too much (without even asking about my diet habits, but oh well) and to stop exercising period until my knees healed, and then to only do low-impact exercise.

I agree that my knees are injured (obviously, the pain tells me that), but is it really that I'm just too heavy to run? Have others been successful doing the Couch to 5k program beginning at a similar weight? Is my being overweight truly the problem, or did I just overdo it by exercising with a bit too much zeal on the off days instead of resting as is recommended with the Couch to 5k program?
