I''m heavy but I can walk miles without getting tired or sweating. Why?

I''m heavy but I can walk miles without getting tired at all and without sweating. It''s difficult for me to run however. I''m wondering why is it that I don''t get tired quickly?

Anyone have any clue?

Holiday Weight Loss Tips - How to Lose Weight During the Holiday Season

To answer both your questions Linda:

You may be able to walk miles without getting tired because you have a lot of "slow twitch" muscle. Women tend to have more than men, and it is partially genetic as well. Slow twitch muscle uses oxygen, oxidative phosphorylation, and can endure. Fast twitch uses glycolysis.

On the other hand, I bet you get tired from doing fast, explosive moves like raquetball, sprinting, and fast aerobic workouts.

To lose weight you need to do AEROBIC (cardio) exercises on nearly a daily basis. This will initiate oxidative phosphorylation (fat burn) within the cells. Get your heart rate around 100-140 bpm for 1-2 hrs. *walking/anaerobic doesn’t do much weight wise.
You also need to reduce intake of sugars, bad carbs and saturated fats. Drink water. Eat healthy. Eating way too little can cause weight retention. You CANNOT lose weight in one specific part of your body, but rather evenly across the body. Counting calories? Just keep ‘em moderate and do the aforementioned.
Some examples of aerobic exercises are running, zumba, dance, hard swimming, p90x, insanity, sports et cetera. Get your heart a pumpin’.
It will take dedication but the payoff is well worth it. Easy things are not worthwhile.
Take care!

• Your body is hydrated.
• Walking is barely worth it. You need to get the heart rate up.
• Maybe you just have good stamina, that''s a good thing though. I am the same way. I''m heavy, but I can walk for about 4 miles before my feet start to hurt and then I go home and rest up.
