The Finnlo Bio Force Multigym is innovatively designed to use a combination of pneumatic pistons & simple physics to make a more lightweight yet smooth multigym (also known as Total Nitrocel Technology
- or TNT System). The Finnlo Bio Force Multi Gym is smooth, solid & with a max load of 100kg per arm, youre sure to be tested, whatever your level of ability. How It Works Heres the physics: When the pneumatic pistons on each arm are upright, you are applying a lot of force downwards on a small surface area which makes the resistance less. As you move the ram to higher resistance, the angle changes which means the same pressure over a larger surface area. This makes it harder to push the hydraulic ram, hence the heavier resistance. A good analogy is to think of pushing a pin into a normal, plastered wall
- pretty easy. Then try to push a thick, blunt nail into the wall
- very hard. The pin tip has a very small surface area, which makes it easy to push in. The nail tip has a comparatively large surface area, so its a lot harder when you apply the same force (you pushing).
