## Questions & Answers

**Q: Can I use it for running 4-6 miles?**
A: We suggest to use the trainer 2-3 hours per time, some people can use it for longer time if they have less allergy to their sweat. It is great to wear while running, I feel the back support so obviously at that time and when you take off the trainer the sweat pours down crazily.

**Q: I’m 5ft and about 170, which size would work best for me?**
A: Medium

**Q: I’m 5’6 and weigh 155. What size what fit me? Also, could I wear this under my clothes through out the day?**
A: You need to measure one inch above bellybutton, compare with size chart and you will know the size. Wear the belt only when exercising and no more than 2~3 hour per time. Don't wear it the whole day, the belt is made from thick neoprene material which is great fo sweating, so it is not breakable type.

**Q: Hello, I wanted to know if this product is shipping from China?**
A: Don’t know but I do know this is the best belt I have ever bought and this is my 12th one
