We need an Explanation on what exactly is going on here. Or at least I need an explanation.

It's important to have space boxers. They need to be able to beat the tar out of those pesky Martians. I heard there's oil on Mars.

Gravity on Mars is about 38% of that on Earth. The apparatus on his back pulls up on him with enough force to cancel out all but 38% of Earth gravity. Thus he feels what it would be like to walk and move around on Mars. Moving the bags back and forth helps him develop coordination in this lower gravity situation.

Of course, a bag that weighed 100 lbs on Earth would only seem to weigh 38 pounds on Mars. An astronaut would tend to "overlift" in that environment unless trained. However, the training shown here does not address that aspect of the problem.

Thanks Marv, That explains it a lot.

Is the design of that suit going to have the Michlin man effect. in the .06 atmospheric pressure? I seem to remember the early lunar hard suits were pressurized too high in the beginning to almost near-Earth Sea level normal then someone got smart enough to lower the pressure to about the same as 30,000 ft
