Do you mean gymnast bridge?
Do them against the wall, working your way to the floor.
Put a band around your hips, to an anchor point and back bend into a wrestlers or gymnast bridge, and back up for reps or time. Progress by moving the anchor point down, move closer to the anchor point, and lights bands.
Handstand extensions. Face away from the wall, and kick up into a hand stand. Move further, and further, or walk away from the wall. Extend the t spine, lock the arms, and keep everything else tight. I saw a video of Adam Glass doing these and I like all handstand variations.
Do them over a yoga/Swiss ball.
Do them on your toes, working to flat footed.
Reverse push-ups. Press for reps from your head on the floor to locked arms.
I am sure there are other options, but these are things I have used. Gymnast and wrestler bridges are great.
