You've seen battle ropes. This is an old fire hose put to great use. It's cheaper, heavier and requires more grip strength. The hose is perhaps one of the best conditioning tools I use. This is Ross VandenBerg, Grand Rapids 7 rugby player. The guys have been showing up every Monday night for some metabolic conditioning at Train Out Pain Chiropractic. They alternated this exercise with trap bar farmers walks. The hose was done for 5 sets 20 sec on, 40 sec rest.
