Today, I learned to ride the rollers with no hands, and clap along to the music. I've spent quite a few hours on the rollers these past few weeks, and my balance and core strength have drastically improved.
It's not a race won, but it's certainly something I'm proud of! I'm a long way between here and playing my violin on the rollers, but considering how less than a year ago I wouldn't allow myself to use the rollers without William nearby to catch me if I fell, I'm going to mark this as a HUGE improvement! Woot!
