How hard I should push myself?

I started to enjoy pushing my limits, thankfully :) I use elliptical cycle for cardio for at least 30 mins a day.

On average I use it at level 8/8, with 14kmh and about 160HR. At the end, for 5 to 15 minutes, I go faster at 16~ and I feel like it's almost impossible to continue. I sortof feel like losing myself physically. I avoid pain in my muscles. When I absualtely have to stop, I stop. I don't use HR but I suppose at that point I'm around 180 or more when I use my hand to count.

Occasionally, I feel like my heart stops beating or slows down for a few seconds on random times. Maybe once a week. But I feel good. Maybe that's related and is saying me to stop pushing?

I'm 100kg, m, 22, taking 1500-2000cal daily. My BMR: 1700.

The answer should be in terms of how hard I should push myself in terms of HR, feeling and post cardio effects.

    Push yourself until you collapse. Or don't. Nobody can tell you how hard you should push yourself. Hence the phrase "Push yourself".

  • How did you calculate your BMR? Using an online calculator (bodybuilding.com/fun/bmr_calculator.htm) the only way to get to 1700 with the other stats you provided is if you are 2' 8" inches tall. May 21, 2015 at 22:29
  • Used a machine in a facility. The exact number was 1760 or something. I have 35% bf

1 Answer 1


With weight training, find a program (I do 5/3/1) and follow it exactly.

In other words, you find a program (there are many, many programs), be honest about your lifting numbers, and progress just as it says from there.

With cardio, no more than an hour really makes sense - you have to live a little, and pumping away on a treadmill for more than an hour will take your motivation away to workout lightning quick. Personally, I do, at most, 30 minutes of cardio - for weight-loss, you want to be burning more calories than you use. That means that cardio can be a means to an end, but it is not necessary to lose a lot of weight in short order.

Lastly, you're 100kg and a man, you should be having somewhere between 2000 and 2500 calories, 1500 really doesn't cut it and you will burn out in short order. I'm 95kg, about 6'2" and trying a 1500 calorie diet really hamstringed my efforts of shedding a few pounds. The key is maintainability - you cannot maintain eating 1500 calories a day, but 2000 is far more doable.

Best of luck!

  • +1 for finding a successful and proven program and sticking to it. Too many people confuse routines with programs, or don't follow the plan, then wonder why they're not getting the results they want.

  • You either didn't read my BMR or don't know what that means. Or am I missing something here? To lose 1kg a week my intake should be 1500 a day.

  • Well don't get defensive, by all means eat 1500, but you will probably lose some muscle and you'll find yourself feeling a little more depressed than usual, but your mileage may vary!
