Visiting 40-50 gyms a year I see a common dynamic. Young girls doing tucked flyaway with spot off the low rail of Bars.
Fun. Easy. Seems, at the time, to work.
But that’s not the best way to teach flyaway. Instead use a wide range of drills that don’t require spotting. Here’s one set-up I like, appropriate for kids as young as age-5.
Click PLAY or watch it on YouTube.
If you don’t have Rings, I’d highly recommend you buy a set. Fitness Rings are very inexpensive. Hang those on a rail at just the right height for your kids.
