"Frog Mobility" -- Get on hands and knees, spread knees but keep your feet closer together, rock back towards your heels and forward.

"Frog Cat/Cow" -- Same position as above, but tilt your pelvis; curve your back up then down.

"Tactical Frog" -- I haven't done this one yet, but it is frog mobility but with each rocking forward twist one of your feet up into the air; IOW rock back then as you rock forward keep one knee locked so that your calf/foot stays in the same relative position as you move forward.
