We have had a beam for three years. Of our 3 daughters, only one is a gymnast. All of the girls spend an equal amount of time on the beam, about o minutes a day for the last two years and eleven months. However, when friends come over, they often use the beam!
We have a piece of blue painter's tape across the middle of the living room. I anticipate a "you might be a redneck" joke....works great for DD though.
My DD has a real nice beam that is about 8 ft long, padded, with suede leather wrapped around it. She did not use it much since it is too short, but the cats loved it. They thought it was great that we got them a $150 scratching post.
Funny though, we have a set of rings in our basement too (and mats, a slide, swings, pull up bar, etc) and they spend more time on those rings than anything else. Maybe they should be male gymnasts?
