Extremely high pulse on exercise bike

[Coeco]

I have been doing the exercise bike for around 20-30 minutes per day in 2 weeks now and i still get an very high pulse (around 180-193) quite easily(Usually after 10~ minutes i get really dizzy/tired/exhausted), I heard its usual for the people that just started but since i have been doing it for a while, i shouldn't get it anymore, or should i? My usual pace is around 18-24 km/h at the first (sometime switching to second) level, The thing im using is a ProShape Magnet bike with pulse meter, calorie counter (Not very accurate), Timer, distance meter and various other things.. What should the pulse be to burn the most fat? I heard the higher, the better but im not sure about that anymore.. Also, some side questions, What is the quickest way to loose fat? Alot of people say running but i cant really run since i got an asthma that is really sensitive against chilly/cold/fresh air and i get really ****ed up if i try to jog outside.. And i would like to know what the most effective way is to burn fat/build muscles on your legs ( Heard that is running with weights etc but i can't do that either=[ )

I usually get about 180-185bpm on the bike. I've always known it's high but never got dizzy or anything so have just never thought anything of it

On a bike you're working on your cardio when your pulse is 166-183. Going above frequently you cycle for too long (= more than 45 seconds) is not healthy because then you start producing acids (anaerobic celbreathing) which makes your muscles sore the next day. The higher speed you cycle, the higher your pulse so just slow it down and you'll be fine. I usually try being around 175 all the time.
Burning fat is all about how long you cycle with a decent pulse and how much carbs you eat. You start burning fat once your sugarsuply has run out. Instead of burning sugar, your muscles then burn fat. So the more carbs you've eaten, the longer you'll have to cycle before you start burning fat. For the burning itself, it's obvious your muscles need oxygen. Thats why your pusle can't be too high either cause with anaerobic celbreathing, your muscles don't get oxygen.
I hope this has helped and good luck!

You cannot burn fat and build muscle at the same (however I personally think there might be possible exceptions to this like when a beginner first starts weight training).

To build muscle you need an excessive calorie intake, this will mean while gaining muscle you will gain some fat also. To minimize the fat gain you need to be very strict with your diet and monitor your intake to have a calorie excess but not too much as too get fat, - the ´bulking´phase (if you dont bulk ´cleanly´ you may have a hard time getting the rid of the fat gain you have invariably made while gaining muscle).

If a competitive boxer wants to build muscle size they are best off doing so for 2-3 months in the off season with not too much cardio and lots of rest, when weight gain is not so important. When coming back to competitive boxing season you will need to reduce your calorie intake to ´cut´ and reduce unecessary fat weight.

The best execise to increase leg muscles is squats.

If your goal is to have stronger legs but not necessarily bigger legs and lose/not gain fat, ride with increased loads at shorter times. Muscular endurance and muscle size growth require different exercises. Boxing training generally can make you look great and toned but not from increases in muscle size, but through fat loss.

Okay so i mainly want to loose fat on my thighs, not really much on the lower leg part, what kind of exercise should i do? (I cant do running because i have asthma) I dont really care about muscles, i just want them to get smaller

Nothing works like running. I had knee injuries and tried it all, and it is bollocks. People who are not injured and do alternative cardio to running are looking for a shortcut. There are no shortcuts in boxing. Get on a treadmill fat boy, and then get on the tarmac.

You're just in bad shape, that's why your heart rate is high. Just walk 3-4 miles a day, every day, until you get your weight down. There's no such thing as spot reduction, to lose weight cut your calories.

That heart rate will be easy once you get in shape. I run 4 miles at ~180bpm several times a week and I don't feel tired or light headed.

He needs to stop whingeing and just run. Get that book about jogging by the Nike guy. That'll get you going.

You can't lose fat in specific places on you body. That's one of the biggest load of bollocks perpetrated upon the general public by all the infomercials hocking those crap "abbsizers" and "miracleslimmerthighs" products.


You lose fat evenly from head to toe and ironically the last place you lose it is the area on your body where you have the most of it.

you're a chick right? lol

Since you're averse to gaining muscles, starve yourself by strict dieting and do plenty of cardio being careful to keep your pulse rate below your anaerobic threshold. Because of your asthma that's going to take a little experimentation. Use google to read up on training using heart rate monitoring.

but what is the difference between jogging for 30minutes and using an exercise bike for 30minutes doesn't all do the same job in the end?
