hard for me to imagine from text, you're on your side, would hip-thrusts be different enough you think? could they work?

so i'm imagining, have your back on an elevated surface (couch, bench, etc.) barbell across your hips and hold onto it with your hands, from a relaxed position thrust up so your back, spine, and legs make a 90° angle with your knee

i've see folks use dumbells and kettlebells, the weighted balls too, i think the benefit is you can use a ton of weight and progress in a straightforward way (increase weight, improve form)
