No doubt about it – some days are easier than others. One day you’ll do a workout and it’s a piece of cake. A couple of weeks later, I’ll do the same workout – same time of day, same conditions – and it’s really, really hard! I don’t know why, that’s just the way it is. It’s always been that way for me.
And some days I can balance on one foot really well and can hold the position for quite a while. And the next day I can hardly hold it for 2 seconds! I don’t know why – that’s just the way it is. I get the same amount of sleep. My diet is about the same. I usually practice my balance at about the same time every day. The weather is about the same. No reason! And some days after a particular workout my knees are fine. And after I do that workout again, my knees are killing me! Nothing is different – everything is the same and yet my result is totally different. I’m still getting the same fitness benefit, I’m sure, but the immediate physical effect is different. If I ever figure out the reason for this, I’ll pass it along!
