Because of COVID-19, I’ve been stuck at home doing no-equipment bodyweight exercises to stay in shape. I needed some variety in my home workouts so I purchased the YMX Boxing Reflex Ball Set. Since I’m a beginner, there’s no cardio benefit since I’m not moving around. Perhaps when I get more skilled, I’ll be able to move and hit the ball so there’s some cardio involved.There seems to be hundreds of different boxing reflex ball sets on Amazon and eBay, but the YMX offered the most for the same price as the others. Amazon’s 10% off coupon made it an even better price than the others.The YMX Boxing Reflex Ball Set came with two beginner balls and two advance balls with cords attached to each ball; two headbands; four extra cords; and a small carrying bag. For the price that most other vendors charge, the YMX is two complete sets for the price of one.I’ve only had the YMX Boxing Reflex Ball Set for a few days, but in those few days, I’ve found myself using it more and more. With consistent use, I’ve improved so that I can hit (tap) the ball repeatedly for 10-15 seconds. The one important thing is to NOT hit the the ball hard. Instead, use a light tap. You also have to keep your eyes on the ball at all times. It’s also easier to punch down on the ball instead of at shoulder or chest level.YouTube has many tutorial videos on using a boxing reflex ball. It looks easy on YouTube, but if you’re a new user, understand that there is a learning curve and you will struggle.For the price and the enjoyment factor, I give the YMX Boxing Reflex Set my wholehearted endorsement.===== SIX MONTH UPDATE & A RECOMMENDATION FOR THE ADIDAS KNUCKLE PROTECTION ====I’ve been using the YMX Boxing Ultimate Reflex Ball for the past six months. I use it almost daily for 15 minutes. Although the ball is soft, the constant and repetitive impact of the ball on the knuckles makes the knuckles sore. A box glove is too bulky and a hand wrap is too time consuming. I tried using a leather work glove and it worked fine except the elastic cord would sometimes snag on the velcro wrist cinch. Another downside is that the leather work glove is not designed to be worn as a closed fist so my fingers would splay out and the elastic cord would get caught between my fingers.The solution that I found is the “Adidas Knuckle Protection Sleeve / Warp”. I wasn’t sure about the one-size fits all sizing, but I wear a medium glove and the Adidas fits perfectly. The pad thickness is perfect. I can still feel the reflex boxing ball hitting my knuckles, but the padding keeps the knuckles from getting sore. The design of the Adidas Knuckle Protection also makes it easier and more comfortable to maintain a closed fist for a long period of time.The “Adidas Knuckle Protection Sleeve / Warp” might not be suitable for punching a heavy bag, but if you need protection for light punching, this is perfect. The ease of putting it on and taking it off the hands is another advantage over boxing gloves and hand wraps.
