## Questions & Answers

**Q: Do you need protection for your hands?**
A: 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.

**Q: Will this fit on a 10 year olds head?**
A: Yes, it’s Velcro attaches to all size heads

**Q: I would like to know as a beginner what's the best way to be consistent? What's the best approach?**
A: Not going to lie they make it seem so easy on the videos but like everything it takes practice me I’ve been practicing for 30-40 min almost daily I’m still using the green ball and I’m getting pretty good at it it’s been about a month now just try to adjust the length of the string to where you feel more comfortable if that makes any sense to you

**Q: Im wanting to start MMA training is this something that would help?**
A: I gotta tell you ... that I simply am not coordinated to do well with these.. I suspect if you are very coordinated it would provide a certain level of unique training for sure. But for me a person without a sporty bone in his body... it will become a regift to one of my grandkids this year!
