...they're still wall push ups (translation: the easy kind ;), but I'm noticing that my upper body has more strength than it did almost a month ago when I started them. Talk about gratifying!
This makes me think that for my fourth exercise, I'm going to choose something else that will get easier as I get more fit, as opposed to the plies and the fidgeting, which were never really hard to begin with. They're still the same. I do them without really feeling any progress, all the while trusting that they're resulting in small benefits over time.
The push ups, meanwhile, actually make me feel stronger.
