    50-70% is your "fat-burning zone" 60-85% is your "cardio zone"...if you're looking to lose fat but keep muscle (most men), you should be around 70%; if your trying to lose weight from fat and muscle (most women), you should be around 85% your target heart rate.

    I am a forty nine year old male. The first stage of my life was full of running, bicycling, and tennis. For the past ten years I have been letting myself go. I haven't been eating right, and I don't know what the word exercise means any more. To make matters worse my father died of diabetes, and my brother has it as well; However, we don't have the same father. My cholesterol level is at lease 200 as of last year. I know in my heart I am headed down the wrong path. Will you help me in my diet as well in exercising routine. I am a vet, but the doctors at the hospital really don't show an interest, because the have so many other vets to deal with. I really don't want to die because of ignorance. Will someone help me in getting a fresh start?

    The doctor's suggestions are somewhat misleading, because it all depends on the exerciser's current aerobic condition and goals, allowing for individual biological variation and the particular activity being engaged in (different sports, different HRs at the same intensity level). Also, the 220 less age formula was made up by several doctors on the way to an overseas conference and is at best roughly valid only for sedentary individuals (mine is ~20 bpm higher than the formula); others should find theirs by testing (test protocols can be found online or via lab testing). Also, max HR gradually declines with age after 40, if not before, so that's another adjustment to be watched. Studies show that aerobic benefit does kick in at about 50% of max HR. Most (smart) endurance athletes do the vast majority of the training (~80-85%) in the approximately 50-75% HR range in order to build a strong foundation. Where exactly in the lower range will vary with the length of the workout (longer=lower), its specific purpose and terain used. Variations in terrain aside, workouts and parts of workouts at higher HRs (~80% ) typically serve specific goals, such as race pace preparation, speed training, mental training. For the average nonathlete, more intense workouts provide variety, personal challenge and help with weight loss. The catch for all is avoiding overtraining, i.e., too much hard intensity, which is counterproductive mentally and physiologically. Also, it should be noted that technique and intensity are inversely correlated: the better the individual's technique in that activity (and thus work efficiency), the lower the HR at any given intensity level. If that's a question, find an instructor or coach.

    When stretching before a workout loosen up before hand,work up a sweat,get your body well oiled up from the inside out,to get your muscles supple so they and your body will accept your workout with less negative effects than what i call a cold turkey start to a negative workout, your muscles are like the old type sponge which when dry would tear very easy and when wet and supple was very hard to tear,plop down and stretch on cold muscles and body and you leave yourself wide open to muscle damage and also negative body workout reaction, warm up that body and experience a much more positive body workout reaction through out your total workout,if you jog you should have noticed that you get into your first mile before your breathing and body rythym starts to get into sync.warm up before hand to get your body ready to perform better,drink plenty of water as you work out,replace liquid as you sweat or wet it out,keep well hydrated.also if you hold your breath during the lift you put a tremendous amount of pressure on your system and as i say possibly bust a gut. kom_ervin@yahoo.com

    I am a busy person. If a 60 minute workout burning 700 calories would be optimum, if I can cram the 700 calories into 40 minutes, am I doing my self any harm?

    I work out about 2 to 2 1/2 hours four days a week. I do and hour and a half of cardio, weights,stretching, and crunches and squats including, then seasonly swim for 30 minutes. Is this too much exercise per day?

    The "8 to 20" scale. WHAT? Why in heck would you start at 8 if 8 is barely moving? Why not start at 1 and make things simple. Or if you want to make it complex, make it a scale of e to pi with moderate intensity at 3?

    I've been working out for over a year and have increased the intensity and length of my workouts. I now work out 1 1/2 to 2 hours per day. I'm having a lot of pain in my knees and noticed today what looks like a bruise on the side of my foot. The bruise isn't tender to the touch. Is this "normal"? I'm in my 40s so I thought the knee pain might be due to my age.

    I think thats great advice for people who take excersizing very seriuosly, When in physical activity I workout very hard I never know my own intensity because I think everything that I am doing is correct. Well I just have to make sure that the next time I excersize that I am careful when exercising. I think its good for my health i just have to makes sure that it stays that way.

    I am not sure about this heart rate formula for moderate exercise. A heart rate of 85 for a 50 year man is hardly moderate exercise. Many 50 year old men have a resting heart rate near 80. Shannon http://arthritis-symptom.com/

    I have exercised my heart according to the above guidelines from 1978 to present. The first heart beat started while I was only 40 years old at less than 50 % of 220 which was 85 beats per minute. Through the years, I increased the rate by 3 beats per minute at the end of eight weeks, starting at 88, 90, 93,95,98,100 heart beats per minute. So at the end of the first 56 weeks, I exercised at 100 heart beats per minute. I continued that pace until I reached 160 heart beats per minute many years later, and I feel just great. The experience lasted all through my life to my current age of 72. When I exercise now, the heart rate is only 130 heart beats per minute. Yes, I watch out that I am not exposing myselt to any heart problems. WOW, I feel wonderful, I take no medical drugs, I eat anything I want, I sleep through the night, I have a lot of energy and I enjoy married life with my wife of 44 years. I would recommend this type of exercise to anyone who would read this message. I would accept any questions concerning what I accomplished during all those different exercise methods I employed.

    what should my heart rate be if i'm on pulse lowering drugs such as verapamil? I have to go really hard just to get it to 104.I am 61 years old and have been exercising regularly for 30 years.
