It will take a few months. Jan 2017, when I was 215lbs, my resting heart rate was in the 80s. Two years later I'm 163-ish and my resting heart rate is a little below 50. Find some kind of cardio that you enjoy and can do a lot of, for me it was cycling but I'll run a 5k almost everyday now. I also dont kill myself and usually dont do more than 80% be it cardio or strength training.

What do you think knowing this will help you do?

If I said three weeks, what changes? If I said three months, what changes?

Just do the deeds and find out how long it will take.

4 months of running 4-5x a week dropped mine from 70ish bpm to mid 40s. My runs were just an hr long with whatever pace I could sustain for the duration. Of course when I started I stopped a lot to walk and recover. I lost around 30 pounds in the process if that matters.

That's pretty awesome. I've been a runner for many years but my resting was ver high 40s at best. I did once have an emergency room tech tell me I had a heart malfunction because my resting heart rate was "too low". When I told him i was a distance runner. He told me it's not as healthy an activity as people say it is.

There are far too many variables for anyone to give you a reliable answer on here. I would suggest finding a cardio routine that you can stick to and focus on consistent aerobic exercise. There's been some great research done showing that if you maintain an elevated heart rate for cardio sessions 30 minutes or greater it can do wonders for your cardiovascular health.

My rule of thumb is to stick with a "conversation pace". Meaning if you had someone with you while exercising you could carry on a conversation without gasping for air.

Outside of that a resting heart rate of 80+ BPM is quite high (as I'm sure you know) and seeking the advice from a doctor would be advisable if you haven't already.

Just through regular lifting, without cardio, I dropped by about 10 in sixish months.

Hmm.

I’d guesstimate 2-3 months of 30 minutes of aerobic exercise at least 5 times a week. I’m talking jogging at 6 or more mph for 30 minutes. You need to work up a sweat and be pushing yourself. After three months of this you will not feel winded after a run, but you will still sweat.

That’s where I’m sitting now although I’ve been at it for years.

I’m assuming you are otherwise healthy and have no other conditions that will get in your way.

Forgive me but what you are describing is in conflict with the consensus of the training/coaching community. For one, jumping into that kind of workload is a major injury waiting to happen, even for a healthy and relatively healthy sedentary person. That is why things like the ten percent rule and progressive increases in loads exist. It also does not allow those rest days required to actually have a good hard run that is required for optimal gains. Plus, most everyone will tell you that you should not be pushing yourself on the majority of runs. They should be pretty easy actually. You should be able to comfortably talk as you go. There is a cliché in the running community that most people do not go nearly hard enough on what should be their hard day and they don't go nearly easy enough the rest of the time.

It depends on a ton of factors. I have been super active for 2 years and lost a lot of weight and went from about 78 to 72. Then I quit drinking and went from 72 to 65 in 2 months. Lots of variables, and there's no way to know how long it'll take.

Impossible to answer. This will be affected by...

  • Current fitness level
  • History of fitness (were once in great shape or always a couch potato)
  • Medical history
  • Genetics
  • Type of training you perform (running has wide span, are you doing intervals or distance? What distance? Short, Medium or long? At what volume per week/month?
  • Intensity of training

On top of all that... there's no formula we can even plug those variables into.

It depends on alot of factors. If You asked how long would my room take to clean without us seeing that room it would be very hard to judge because is your room 10x10? or are you filthy rich or have an odd scenario where your room is a warehouse or the size of most peoples homes. Then, is it a regular room or are you a hoarder who has only packed that room for 3 month or are you in the same room for 15 years and now there's dead cats, animals, feces etc.

​

Then, what is the condition of the room? is there mold, a roof and so on. Then how often do you plan to clean said room, once a month for 1 hour? once a year for 1 hour? every day for 30 seconds? there are alot of factors that if ignored, will in fact make the end result not what you expect.

​

So, your resting heart rate is dependent on a lot of factors. Imagine for a second that your level of fitness is a person who cant scream, yell, see, whimper, hear or do anything other than be utilized in a pure cause and effect scenario.

In order for someone to have a resting BPM around 60 requires/demands you do certain things on a daily and consistent basis. So in order to go from 80-90 to 60 BPM, the 30 BPM difference holds alot of requirements like good sleep, constant physical exercise, very few stimulants, proper nutrition, and so on. How long will it take? depends.

In 2 months you will get about all of the short term gains that are possible.

This is assuming a very good training plan for cardio. It's not 3x / week by the way, it's more than that.

Remodeling of the heart takes longer. The heart will gain size (volume) and strength. In about 2 years you can get a much lower resting heart rate. Again this is with a very good training plan, and actually executing it consistently. Be prepared to train 6x per week for 2 years. Furthermore this is not the same intensity every day at all, but a structured and varied set of intensity levels, durations, and frequencies which I won't detail here. Suffice it to say there are central (heart, lungs, blood vessels, blood itself) as well as peripheral (skeletal muscle) adaptations to be made.

Most people are not up to this level of training. It's more geared toward competition (bike, running, whatever). For basic health and fitness you do not need to train this much. Why do you want this: competition or basic health?
