If I can maintain my target heart rate while lifting weights, how come it is not considered aerobic excercise?

because weight lifting is such an intense activity and you use so much power to lift, it is not an aerobic activity. the oxygen just cannot get to the muscles fast enough to produce enough energy. what happens instead is carbohydrate is burned because it is quick to burn and highly available.  Creatine is also a very fast source of energy and oxygen is not needed. \nyour body really wants to use oxygen because it is a whole lot more effecient, so it is going to up the heartrate in an attempt to get oxygen to the muscles. But, because the exercise is so intense it overrides the energy provided through oxidation and uses anaerobic (w/o oxygen) sources of energy

Aerobic exercise is cardio, such as jogging and cycling. It gets your heart rate up. Anaerobic is weight training, such as lifting weights and leg presses. With weight training, you do a set amount of reps which become difficult near the end. With aerobic, you keep at a steady pace.

It used to be that the formula of 220 minus your age was the "gold standard." But there is a growing school of thought that age-based formulas are not the best strategy.\n\nMost methods are based on achieving targeted exertion levels (zones) defined by percentages of the maximum heart rate (Max HR).\n\nMax HR is the highest heart-rate value achieved in an all-out effort to the point of exhaustion. Obviously, it’s rarely the goal of any workout to take you to a point of all-out exhaustion, but using percentages of a Max HR to determine the appropriate intensity for a given workout (or series of workouts) can help create more efficient and effective fitness routines. For example, working out at half the Max HR is great for improving health and increasing base level of fitness, while working out at 75 percent of Max HR is a great way to improve cardiovascular capacity and endurance.\n\nBut the best method for determining Max HR remains a hotly debated topic. The main problem is that Max HR is not influenced so much by age as by genetics. In fact, most people of similar age do not have the exact same Max HR.\n\nThere are basically three methods. Two of them require professional training equipment or resources. The following formula is the most reliable for do-it-yourselfers: Calculate 210 minus one-half your age; minus 5 percent of your body weight (in pounds); plus four (for men) or zero (for women). This formula has been tested on thousands of people and the results typically fall within five heartbeats of a person’s true Max HR. Of course, even this formula leaves something to be desired, but it beats the simple “220 minus age” hands down. To calculate your target heart zone, multiply the Max HR number by 65% and then by 85%. That represents the target heart range.

In order to pump more blood to your body to keep it moving.\n\nWhen you are exercising or physically exerting yourself, your muscle cells need more oxygen and more energy, which is transferred through the blood. Your heart beats faster in order to compensate this and to pump blood more quickly.

Yes it is true\n\nYour body "gets used" to whatever exercise you do whether it be a step class or strenght trainig.\n\nIt is very easy to vary the patterns thought.  For example - instead of doing straight bicep curls break them into "3" - pauseing intentially on the way or do it will barbells as opposed to a bar - or go slow or fast.\n\nSimilarly with aerobic - if you run - inject high knees peridodically or run laterally or backwards\n\nPlay with frequency, itensity and duration

It's a great form of exercise with no impact on your body. It's a cardio workout as well as a fat burner. You develop balance, work your muscles, and it is an excellent ab and lower back workout. You don't perspire excessively, it burns your blood sugars and its usually in a relaxing environment. For me, it's like meditation. My mind can focus so much better when I'm swimming.

Cardio.  Skip the weight lifting.  Not good for hight BP

If you can, try to fit both into your routine. Running burns calories while you exercise, and is good for your heart. Weight lifting will burn more calories in the long run, though. While you do not burn as much as running does while your exercising, it does add more muscle, which increases your metabolism, which burns more calories at rest.

High intensity exercise for short periods of time is actually much more effective at building endurance than low intensity exercise for longer periods of time.  Jumping rope is excellent for building cardiovacular endurance.\n\nThis is easily measured and calibrated with a heart rate monitor.\n\nNote that I said endurance....not health.  Moderate regular exercise is heart healthy and prevents cardiovacular disease.  High intensity workouts build endurance but aren't good for a healthy lifestyle.  The old joke about Jim Fix comes to mind.  He had incredible cardiovacular endurance and dropped dead of a heart attack while out running one day.  They found him surrounded by a bunch of smoking fat guys going, what a shame....and he was so young.

A cardio workout burns calories. The harder the workout the more calories burned. One of the absolute best workouts for fat burning is to job at a pace above 6 miles an hour. \n\nWeight lifting is also great for burning calories, but it does not teach your body how to maintain energy while doing activities. Cardio workouts allow you to do things like play basketball without getting fatigued. If all you do is lift weights, you wouldn't be good at fast paced sports because you would get winded easily.\n\nBottom line, Cardio burns calories, fat comes from stored calories. Eat Less, exercise more.

You might be working out above your ideal heart rate. Get a monitor and figure out what your ideal one should be and try to stay around that.

It sure is. Anything that increases your heart-rate is considered a good cardio workout. Just remember that a cardio workout should be no less than 20 minutes.

You know this answer -- we all do.  But few have the discipline to do it.\n\n30 min to 1 hr of cardio and strength-training every other day.  Push to your own limit.  When lifting weights, use good form, slow and steady pace -- less weight and more reps for leaner, longer muscles -- heavy weights with reps to the very edge of fatigue for bulk.\n\nEat lots of fresh fruits and veggies, and avoid salt, trans-fats and processed foods.

Hi it sounds like you have a solid cardiovascular program going. Have you looked into purchasing a heart rate monitor?  \nWhen starting out lifting I always tell my clients lift moderately. Lift what you feel gives you a solid feeling. If you feel like your wimping out you probably are. If you feel like your arms going to fall off on the first day I'm betting your lifting to heavy. The goal is to build a varying routine that your body has trouble adapting to. While not killing yourself so you'll come back tomorrow. This type of lifting  will burn more calories, as well as help you gain strength and power faster. Id suggest you look at the book  The New Rules of Lifting. The have detailed workouts for any level of lifter, even the most novice. It has picture diagrams of all of its exercises and most importantly its workouts vary so your not just doing chest press and arm curls all the time. I hope this helps. Good luck!

hi bonny\nnothing is worng it is only because u don't drink water enough.\nDuring workout i think you  take lot of break in between  sets... which brings down  heart rate and cools down your body so you don't sweat this is one of a reason...\n\nOR you maybe working in aircooled GYM which is another reason

Well-trained athletes CAN pump more blood from their hearts at maximal exercise, but the main reason they tend to have slower heart rates is because their muscles are much more efficient when it comes to extracting oxygen from their blood.  Therefore, for the same amount of work that their muscles are doing, not as much blood flow is needed to supply the necessary amount of oxygen.  Therefore, their hearts don't need to pump as fast or as hard to keep the muscles well-supplied with oxygen.\n\nThink of it as two people standing on a riverbank.  One guy (the non-athletic heart) is using a crappy fishnet and can only catch 10% of the fish that swim by.  If he needs 10 fish an hour to survive, he needs to have 100 fish swim by to in an hour.  If the guy next to him (the athletic heart) has a brand new fishnet that can catch 50% of the fish that swim by and HE needs 10 fish an hour to survive as well, he can do just fine with only 20 fish swimming by every hour.  Does that make sense?
