Back-coiling is a game changer. Every other coil is reversed, leaving a net zero in coils. It just pulls out straight.

Orbits are all about speed, not height. To deorbit, you need to reduce your speed at the highest part of your orbit. This will lower the lowest part. You jump off the back. You would need to jump FAR harder than your legs are capable of though.

Unfortunately, the sheer speed will kill you, without shielding. As you hit the air, you are going so fast, the air can’t get out of your way. You compress it ahead of you, that heats it up. It gets hot enough to melt most metals. The air will cook you, long before you get slow enough to use your parachute.

For comparison, terminal velocity (max speed you reach falling) is around 200km/h. Orbital velocity is 7km/s or around 25200km/h.
