I used to go to the gym 2-3 years ago. But now I rarely go, because after a break I can't really do any cardio: after 7-15 minutes at a treadmill I get really tired. I usually go 10-14kmph and going slower just feels wrong. After 15-20 minutes once I got dizzy and it hurt breathing in, but I was going slightly faster than usual. I also have a pretty high heartbeat when I run
So my problem is that in order to feel less tired running I need to run. But most I can do is 15minutes. I've tried 5-6 times recently, but it's always the same thing.
How do you deal with this exhaustion? What are the tricks to quickly get your stamina back after a long break. Maybe I should try something else, rather than treadmills
I want to get back to weights, but before that get my stamina back. I'm 21, weighing 105kg, 192cm height. So I would like to get rid of 5kg before I start doing weights again. I used to be able to comfortly run 30min before doing weights and after for another 30min. Weighing 90kg at a comfortable stage, with no clear sight of being overweight.
In response to duplicate - My question is not how to lose weight quickly, but how to quickly regain stamina (possibly when health situation isn't ideal).
