My boys (3y and 1y) have been going here for a few weeks. The instructors are very friendly and accommodating. They have several gymnastic type fixtures and obstacles such as un-even bars, parallel bars, and balance beam.
The classes work on teamwork, listening skills, ball handling and hand-eye coordination skills, and climbing and balance. The instructors do a really good job reeling in the kids and working with them.
You have to pay for a membership fee and then for each semester classes. With the membership come exclusive open gym and events throughout the month. We just participated in the Halloween event and it was a blast for the boys. If you're looking for something for your kids to participate in and be active, I highly recommend the Little Gym!
