Many yoga poses (asanas) are so-called balance poses. In one way or another, you’re balancing yourself in an at least slightly unusual way. This might be as simple as standing on your toes while bending your knees (a variant of Chair Pose [utkatasana] that’s sometimes call Awkward Pose) or sitting with your torso and legs raised (Boat [navasana]), or as complex as advanced as Flying Man (Eka Pada Koundinyasana).
Two of my favorite balance asanas are Tree (Vrksasana) and Lord of the Dance (Natarajasana). I’m still not very good at Lord of the Dance, since there’s some flexibility still lacking. It’s fun regardless, and certainly challenges my balance. Tree is often good and solid. Lately in class we’ve occasionally been doing a variant, Bending Tree (I think of it as Willow Tree). That’s certainly more of a challenge as one’s mass shifts over the foot in a way that maintains the center of mass directly above the foot.
Most of my practice has been with a hard floor under my mat, either hardwood or concrete. I recently was in a different room and had my mat on a nice carpet. After about a week and a half of that, I had to return to the room with hardwood floor.
I noticed a big difference in the way my balance poses felt, especially Tree.
On the hard floor, I was initially using just the big muscles in my lower leg to balance, along with those of my upper body to shift my center of mass. I wasn’t aware of what I was doing, but that’s what I was doing. As I improved my balance and my awareness of my body, I started noticing that my feet were getting a little tired when I held Tree for a long time. I realized that in this pose I wasn’t using the big muscles in my legs and upper body much anymore: my center of mass was staying generally right where I wanted it. I was using the small muscles in my grounded foot to make small adjustments and maintain my center.
I wasn’t sure how I would like it when I moved to the carpet. I was concerned that it was too soft and too squishy, with too much give. I was concerned it would be harder to balance, whether in Lord of the Dance or in Tree or in Eagle (Garudasana) or in Figure Four (Eka Pada Utkatasana). Though it took me a little while to get used to it, I was, indeed, able to balance just fine. In fact, I noticed that the small muscles in the sides of my grounded foot were pushing against the carpet a little. When I moved back to the hard floor, I kind of missed that feeling, that ability to almost dig my foot into the carpet. Instead, though, I noticed that the small muscles in my feet were working a little harder than before.
A delicate balance.
