Today:
I did ~15 minutes unbroken of crawling variations and "floor work," including:
Baby crawling
leopard crawling
twisting bear
table top/crab walks
AG walks*
Plank walks**
Putting info about the last two here because I'm not sure if anyone has heard of them, AND I think they could be good moves to toss into crawling sessions for extra spice or intensity. Google will turn up some videos.
*AG walks are used typically in gymnastic training, and I haven't done them in a long while. After today, I may make them a regular thing, as straight arm movements don't bother my shoulder as much as bent arm movements. AG walks are essentially a reverse plank (so chest to ceiling) where you put your feet on something that slides and push yourself forward. They are awesome for shoulder extension, posterior shoulder musculature, and triceps.
**Plank walks are essentially the opposite of AG walks. You get into a plank, put your feet on something that slides, and drag yourself across the floor. Some videos have people on their toes; I prefer to point my toes so that the tops of my feet are on the slider. I find that this prevents the reflex of pulling with the hip flexors. The other cue that is important here is to push away really hard; use as much protraction as you can.
If anyone wants some easier progressions for those I can provide them.
