Why? The bungee cord is only needed for earth gravity.
It's not a symmetric exercise, look at the feet. You'd probably want to keep the overall workout balanced by alternating periodically?

With a hamster wheel, aren't you basically running in one spot near the bottom? If so, do you know what causes the dizziness?
Because you're looking forward at the platform that's moving down and toward you. Kind of like if you were to stare down at the belt of a treadmill while it's moving - it would be disorienting after a while.
Because even if your claim is correct, and the conflicting visual input is disorienting, the Moon-dweller on a similar contraception could just close their eyes.

#73I didn't see any mention of having a spinning surface. A tapered cylinder "gravity gym" with adjustable angled walls, and variable speed spinning, could smoothly create much greater "gravity". Spin gravity would also enable body weight exercises, core exercises, stationary or small area cardio like exercise bikes, VR games, yoga, etc. Even sleeping.

A train or roller coaster on a slightly tilted circular track would probably do the job. A slight tilt would just move the gravity vector orthogonal to the floor.

Doesn't this boil down to a claim that blind people are incapable of running on a constant upwards slope due to motion sickness? Because even if your claim is correct, and the conflicting visual input is disorienting, the Moon-dweller on a similar contraception could just close their eyes.
Blind people only have 2 out of the three signals so they might be less prone to motion sickness.

#76Is there a reason something like a water rower wouldn’t work on the moon? Possibly with a weighted vest or a weighted seat. Rowing is pretty full body and doesn’t seem that reliant on gravity.
I'm always baffled that these studies don't put more emphasis on resistance training, since the main issue is that your body no longer has to resist the forces of gravity on a day-to-day basis. In theory exercises like the major compound lifts should go a long way because they stimulate almost every muscle in the body. You get a lot of sustained muscle growth out of doing big lifts even just 2-3 times of week. Of cou…

Wild idea: build one on earth to simulate 1.1G (or higher; whatever would still be comfortable) and put gyms, hotels, swimming pool, living quarters, etc. in it. Being in it for extended periods of time would build up muscles and bones. That would likely be something that fitness people and professional athletes would be interested in. And it's a good dry run for building and operating these things on Mars and the Mo…

A rower wouldn’t provide the same impact forces on the feet, a key driver of the physiological processes that maintain bone density in the legs, hips, and likely even spine.

#79Is this the same concept as the running scene in the film 2001: A Space Odyssey?
Running in small (10m) diameter cylinder increase gravity significantly without need to spin the cylinder.
Anyway to minimize effects of Coriolis force in spinning cylinder, I think that the size of the cylinder would be significantly larger than the size in the movie.
Re: Horizontal running inside circular walls of Moon settlements
#80Finally I get to be that guy in the comments with a weird about of relevant experience. I built the world's largest hamster wheel in 2012[1], a large rotating circular platform ~6m in diameter. It was a fun and unique experience to run on for a short amount of time, but most people would get dizzy after a few minutes of jogging on it. The curved platform also turned out to be a bit of a tripping hazard. It was more o…
