The “Grudge Leash”…my tethering tool for swim diagnostics is unique because it captures a continuous stroke to failure. Adding underwater video and analysis gives you all the tools you need to improve your swimming! I also post your video to Youtube so friends and colleagues can add their informed opinions if you so choose. Your stroke CAN’T hide from underwater video!
This video demonstrates another popular way to incorporate the leash into your training……especially while nursing an injury or needing just a day of doing something different!
