    I actually think the cold makes exercise easier. So much of the circulatory system is used in cooling off the body and shedding heat generated by the mucscles. That being said, it's much easier to shed heat when it's 50F or 20F or colder with low humidity than it is when it's 85F and high humidity. Heart rate will be lower even with much harder effort than when it's hot and humid.

    I still don't get it. Maybe it's the activity. I've got 6-years of personal heart rate data logged. Same thing every year. It gets colder, my average run pace gets faster and my average heart rate for the workout is lower. It get's hot with humidity, I run slower and the heart rate is higher.

    I usually will wear pullover sweater/jacket with sweat pants...apply some tigerbalm or woodlock to warm up the muscles and tendons...when I'm about to break a sweat, then I go out to train.

    This seems to help me.

    Training consists of Muay Thai, BJJ, weight training, and mountain biking

    Would like to be in good shape by my 36th Birthday (07-07-2013)

    This is only true if your muscle temperature drops with air temperature. Once you have been exercising for more than a couple of minutes, your muscles are plenty warm. The fact that you can overheat while exercising even in freezing cold weather shows this pretty plainly. If your body is making so much heat that you have to work to dump it to the environment, you do not have a problem with cold hemoglobin, LOL.
