How to hula hoop
Put on athletic clothing.
Wear a tight-fitting shirt and pants so it'll be easier to hula hoop and so the hoop won't get caught on any loose clothing.
Comfortable shoes will also make it easier for you to hula hoop.

Select from:

b). If you feel like your hoop needs an extra load, go ahead and buy it at your nearest sporting goods store. Most practices and practice schedules are set for wednesday and friday, so you don't really need to worry about bumping into someone if you don't have the sport's size set.

d). Select a hoop that's right for you. The hoop should be made of sturdy materials, so it'll be more fun to hoop with clothing than wearing high-top clothing that will snag on any loose clothing.
c).
