Seeking Two Scenarios

Hello everyone, I’m a newcomer to this forum. I feel a bit nervous because it’s my first time posting on a bondage community! I’ve been reading up on self-bondage and am searching for “gymnastic SB” scenarios. Let me try to be clearer (apologies if my English isn’t perfect). I tend to sit too much, which causes significant pain in my back and shoulders. I need to engage some gymnastics or at least maintain a straighter posture; currently, I slouch like this: Image

I’m looking for scenarios where I am forced to keep my back and shoulders aligned (and ideally able to work on the computer since I do some hours at home), as well as one involving an exercise prescribed by my physiotherapist. Failing to stay upright brings discomfort, while doing it correctly yields pleasure. The specific exercise requires me to be on all fours, pushing my shoulders back while lifting one arm at a time and holding that position for 30 seconds each repetition. I hope this makes sense.

I hope this graphic helps illustrate: being on knees with the left hand down and raising the right hand will correctly align my left shoulder. Image

All these things feel quite tedious to me, so I’m seeking ways to add some spice. My equipment is minimal…

• two 1-meter chains with fabric loops on one end and karabiners on the other (essentially dog leashes, which work wonderfully as crotch chains)
• handcuffs made from a short chain about 50 cm long (I added foam and fabric to prevent wrist marks)
• clothespins (wooden and plastic varieties)
• strings
• one back/shoulder posture corrector (though it’s slightly too large for me)
• one adjustable shoulder support brace with velcro closure
• padlocks (roughly five share the same key, while one has a different key but is somewhat rusty; there’s also one combination lock)
• four vibrating massagers (one pillow type, one pocket-sized, one for the neck, and one stick-like model)
• two small nipple clamps constructed from tweezers and elastic bands
• homemade fabric & foam bands with laces (to use as ankle or knee straps)
• a 1-meter length of rope

I can utilize my single bed and a large radiator. Above the radiator is a window (shutters will be closed!) with one handle.

Exclusions: I do not want gags, no breath control, staying indoors only, no other people assisting, no arduino devices, and no nettles. I lack ceiling hooks. My wardrobe poles might support my weight without breaking—I have two of them (one near the window, one further away near the door)—so they seem usable if not bearing all my load.

Also, I am female and quite slim.:) Thank you.
