Ask HN: Fitness without money and gym

I want to build muscles and good fitness, but I don't have enough money to join gym. How to do it?

Start with the 30-Day Plank Challenge.

Since you mentioned good fitness, start recording what you eat in a food diary. This is the first step to eating healthier.

Also, get away from the damn screen and go take a walk.

Not to market this app but I highly recommend "Sworkit" app. Tag line: "No Gym, No Excuse"

PS: I did workout today using that app.
