Judging progress can be difficult. People talk about a kind of zig-zag in tango. One lesson, everything clicks and is perfect and you feel you’re doing fabulously. The next, everything feels terrible and nothing works and you feel you’re a lost cause.

I’ve been doing pilates for only a little longer than tango, and there it feels even harder to see progression. Maybe an exercise feels a little smoother here and there, but mostly I rely on our teacher’s assessment.

But every now and then …

I can balance really well on a bicycle or motorcycle: I often used to win ‘slow races,’ which are all about balance. But I’ve never had great balance when standing on one foot. I generally carry out a site survey and formal risk assessment before putting on a sock. I knew I’d have to improve my balance for tango, so asked our pilates teacher for one lesson focused on that.

Aside from standing on a balance board for a while, it didn’t feel like much of the lesson was overtly geared to that, and trying a balance ball at home afterwards, I could see and feel no visible progress. Steph was able to stand on it doing a fine impression of a rock; I looked rather more akin to a yacht being tossed around the ocean in a force ten gale.

But side-steps in my next lesson did feel more solid. And putting on my sock the next day, I discovered something amazing: I was able to stand, almost perfectly still, on either leg! When I got back on the balance ball, I was almost stationary on that too.

I could even follow Steph’s lead into a yoga move, lifting the other leg up and alternating between holding it in front of, and behind, me. That’s something I could never have imagined would happen so quickly. I was so surprised I almost fell over.
