Instead of having to get down on the floor every time you want to work your abdominal muscles, build your own sit up bench for workouts. A properly constructed sit up bench needs an incline surface that remains stable against your back and a place to anchor your feet to ensure the proper form. The sit up bench also needs to be long and wide enough support your body.
Items you will need
- 2 bent pieces of thinwall electrical conduit
- 1 straight piece of thinwall electrical conduit
- Wooden board
- Pipe insulation
- Furniture ends
Use two bent pieces of thinwall electrical conduit for the base of the sit up bench. These tubes should be 5 feet long and 1 inch in diameter. The ends of the tubes will form the legs of your bench. The longest leg needs to be 17 inches, bent at a 50-degree arc, while the shortest leg needs to be 12 inches, bent at a 70-degree arc. The shortest legs are where your head will be when doing sit ups.
Drill bolts, preferably 1/4-by-2 1/2 inches, through the middle of the legs and the base of the 2 thinwall electrical conduits to hold them together.
Place a 20-by-11 1/2-inch wooden board over the center of the tubes so that 4 inches of the end over the board extend past where the shorter legs begin.
Drill bolts, preferably 1/4-by-2 inches, through the wooden board and into the tops of the two pipes.
Attach a 16-inch piece of thinwall electrical conduit, running perpendicular, about 8 inches up from the bottom of the longest leg. Secure it in place with contact cement and a bolt, if needed.
Wrap the ends of the 16-inch pipe with pipe insulation so that it is more comfortable against your ankles when you are performing a sit up. Place furniture tips on the bottom of the legs to keep the bench from sliding.
