## Questions & Answers

**Q: Can you skip on concrete surfaces?**
A: Yes, the speed cables that come with the Sonic Boom M2 speed jump rope can be used on concrete and tarmac. However it will deplete the polymer coating faster than on smooth surfaces. Also, to protect your joints, if jumping on solid hard surfaces like concrete, you should always use an exercise mat. That way your hips, knees and ankles don't feel as much impact over prolonged jumping sessions.
