If you’re looking for a way to add some high-intensity reflex and coordination training to your workout regimen, and you don’t mind wearing this admittedly somewhat funny looking headband, the reflex ball is a must-have.
Easy to set up and use at home, It mounts to your headband via a flexible string, and using it helps build accuracy and speed while giving you a full body cardio workout at the same time. Unlike a traditional top-mounted speed ball, this one bounces around unpredictably, flying out of reach when you hit it and then flying back at you like a yo-yo. The harder you hit it, the faster it comes back for more. See how long you can keep it in the same spot with quick left-right jabs.

An easy addition to any boxing, kick boxing or MMA fitness type workout, this reflex ball helps train your brain at the same time as you burn some calories and build muscle. Because the reflex ball moves around on an arc, it helps you train the fast type II fibers in your calves and pecs as well as helping build core strength and, if you keep at it long enough, endurance too. And even a brief bout of strenuous exercise has been shown to boost focus and help build neural connectivity, so this high-speed mind body workout can help you kick ass at work as well as in the ring.
It’s also great for hand-eye coordination and helps with your balance, focus and concentration too. And if you play squash (does anyone play squash anymore?) this is great at-home practice. Just make sure you’ve got the hang of it before you bring this with you to gym, or else it will not only provide a great workout for you, but great entertainment for your friends. Haymakers are, probably, not advisable with this thing.
This reflex ball from Kaqulec boasts a 4.5-star rating from dozens of reviewers. And at just $10, it’s a steal for a new, full-body workout you don’t have to go to the gym for.
