The Speed Demon is an incredible tool for building speed and endurance with your speed bag.  It mounts on your speed bag platform and bounces light beams off your speed bag to track its every movement, all without ever touching your bag or swivel.


Its digital display will tell you how fast you are punching (punches per minute), the number of punches you've thrown, or motivate you with its challenge mode and time trial mode. 


Be sure to also check out the Speed Demon XT - this advanced version of the Speed Demon wirelessly connects to your compatible smartphone or tablet to log your workouts, provide analyical data, and determine your speed endurance ratings (see below).


Remember that feeling you had when you first started hitting the bag?  You can feel that again when you go a little crazy with the Speed Demon.  After knowing how fast you punch, you will only want to punch even faster!  

Or maybe endurance is your thing? Check out this video.
