If your trying to increase your conditioning and improve your explosive strength from your legs pushing and pulling a sled is a great alternative. Some of the sleds I've seen have been priced as much as $180, USD plus shipping, with pushing sleds up around $250. Ross also has the other extreme where its just a child's crazy carpet and some rope. Sledward (i blame Brandon for the corniest name ever) falls somewhere in between the two extremes.
This project is a lot more complicated then my CHINS bar on the go, you will need to be able to cut and weld metal, and measure. Special thanks to Brandon for helping on this, i could have never opened all those packages by myself.
Supplies
3 four foot lengths of thick walled 1x1 steel tubing
2 feet of regular walled 1" od round tubing
2 Hooks
1 Length of rope
2 Carabiners (sp?)
1 Thick nylon tie down (used for a harness)
Tools
Welder
Angle Grinder
Cut off Saw (optional)
Dimensions
The width between the main poles is 12", the top bars are 14" for added strength. All tubes are 1" round or 1x1" square aside from the small one the pole for the plates sits on. Both front and rear kicks ups are 45% angles, the top hand bar is mounted to 4" tubing also cut on 45% angles to make it vertical. Kicks ups are used to prevent the sled from digging in and becoming a plow.
This sled was made very high so that we will also be able to push it without needed to get super low to the ground. The pulling mounts were welded about 5" from the ground to prevent tipping. The weight stack was also placed near the rear to prevent tipping and to make pushing more difficult. The sled was made longer then needed for stability and for the option of adding a second weight stack.
Hand bar, for pushing
Rear Kick ups
Mounts and Dressed welds (only the welds that contact the ground were grinded smooth)
Harness
Training Vid coming soon
