She can be very aggressive, but is nice and refreshing even that they didn't make him a total pushover, I mean if you look at most of this chapter, our MC has become very comfortable with her, I feel like they got more progress than they did in "Shachou to Sake to Hoshi / Me and the Prez, Drinking Under the Stars" did in 50 chapters.
Oh come on! What was the stretch that helped the lower back? All I've found are basic exercises.
"
short bridges involve pushing through the lower limbs, and are the gentlest way to begin spinal
training because in everyday life we usually activate the spinal muscles via the legs. We do this sim-
ply by moving around, bending down, etc. The act of keeping the trunk straight at the top of the
short bridging movement stimulates the spine and hip muscles with hardly any pressure running
through the vertebrae. As a result this exercise is wonderful therapy for those who have suffered
disc injuries."

Bridges.
