Hello.

I like doing sit ups. Until now, I've been using the bedframe as a thing to hold my legs down while I do them. However, this is no longer an option, because the bed keeps moving. What can I use/build to hold my feet in place?

Keep in mind, space is limited. The more compact and simple the device, the better.

You don't need this contraption.

Just lay on your back and then raise both, your back and legs at the same time and touch your toes with your fingers.

Try this exercise, it works just the same.

this or leg raises or hanging leg lifts

You are a damaged man

I've used heavy dumbells for this. Hook your feet under and they anchor you. Not comfy but it does work

This.

mount a pullup bar near the ground and tuck your feet under. Can also spin around and do dragon flags.

Not doing it right

I wouldnt recommend nailing your legs to the bed. Maybe a long wood screw if you have a nice long extension. 

Ideally you could use a construction adhesive or concrete to keep your legs permantly in place. 

Id also check local building codes as you wont be able to escape the inspectors if you did a good job. 

Good luck OP.

My country's military uses the legs held down style situp in it's fitness tests. Nothing wrong with it if you balance out your routine

raise your legs up then do crunches, better core activation and you dont need any contraptions

Do squats...you will be forced to get stranger abs with more weight on your back trying to kill you.
