Shaped like a vault top, springy like a Mini Tramp and as useful as a vault board, the T-Trainer will quickly become your favorite training aid. The top surface is made with our Xtreme bed material and measures the same as a vault table, (3' x 4'). Place the T-Trainer in front of the vault as a springboard or use it at a bar station to improve circling, handstand, or seat bouncing drills.
