מדוייק!

So any way?

Cardio classes are a Step in the right direction.....

So simple! And what all the best athletes do! Everyone else is trying to sell you quick fixes. There are no shortcuts! Do the roadwork or stay mediocre at best! Ali, Tyson, Mayweather, Pacqiaou.. They all did it because it is the way! Even Rocky did it!!

Wtf? If you will stretch your heart you will face a tons of issues with it during old age.

Otherwise you will get stretched heart that works badly in calm conditions
