Front Handspring Vault Drill

I've used a similar setup to work on Kasamatsu-full and Kasamatsu-1 1/2. Just to add, my gym does not have a rod floor. I would place one springboard on top of the other and vault in to the pit. I feel this method helps with vault-entry position as well as blocking technique and heel drive. If I did not get a good block or if I twisted too early, it let me know very quickly! After just a week of this, I noticed a difference in the height of my vault, as well as being in a better body position for the double or 2.5 twist.

If you don't have a rod floor, you can still use a spring floor. I've seen it done that way at a gym that had no access to a rod floor. The only necessary equipment is the springboard, mats under the board, and a mat behind the board.

If a coach doesn't have the luxury of a rod floor like in the demonstration what would you be using instead? Or is this drill only good if you have this type of equipment

No, it works just fine.

wont the board slip on the floor?

that little girl demonstrating has really good form
