No, This is not a slimming workout program !
These are Stranded in Outer Space features that make the experience more immersive an fun !
Stranded in Outer Space now allows you to improve your character strength by cutting trees, breaking rocks, etc…
The weight system takes strength into account, allowing you to carry more stuff, jump (or re-side-jump on a wall) higher or simply punch harder !
But watch-out ! The total weight of your gear and items can slow you down, which means that traveling light while being strong can give you a nice little speed advantage.
