Interesting. I don't agree. First, for a 6'2", I don't think 300 pounds is too much that diet and exercise cannot reduce it without going to the extreme of surgery. It isn't the actual weight that is important. It's the composition of the weight.
The beautiful thing about the body is I don't think it would allow him to go out and kill himself running a marathon at his height and weight. Of course he has to start out slow and move up. If you were and absolute gym rat and laid off for 6 months I'd advise the same thing.
Most people who don't run can't get more than a half mile first try anyway. If they don't swim, they won't get even 1 lap (in an Olympic pool) without stopping.
I DO agree he should see a doctor.
I agree, Gunny. Very heavy people can exercise without automatically leading to a heart attack. But, like you said, he has to go slowly.
Probably the worse outcome from advancing exercise too quickly in a heavy person is likely orthopedic problems, such as ligamentous or meniscal tears in the knees.
That's what I was thinking. Knees, ankles and feet.
Head, shoulders, knees, and toes...
