Stretched out (on the rack)

Waking up this morning, was aching in places I hadn't really ached before.  The Monday night session had been tough as it was hot and sweaty, which saps me quicker than other conditions and had needed more breaks than I usually do nowadays.  The aches afterwards though were as if had been stretched out, as I imagine, on a rack.

I tried to think back through the lesson as to what might have caused the aches: We did fundamentals (punches, receiving, kicks), a lot of Kata practice, pad work and Nunchaku.  The latter was fun, but as it was only the second time I had used them, might have resulted in some bruises and soreness.

There was nothing there that should have caused the stiffness, then my my mind went back to the stretches and I think I found the cause.   Our Sensei have started introducing different stretches, and two in particular stood out:

1)   Linking arms with partner,
      back to back walk down to sitting position,
      partner one leans forward, whilst partner two arches 
      back, so is stretched out on back of partner one,
      hold for 10 seconds,
      back to sitting position,
      partner two and one swap roles in stretch, partner one
      on back of partner two and hold for 10 seconds,
      back to sitting position
      back to back walk up

2)  Linking arms back to back with partner
      partner one squats and leans forward,
      partner two arches and is pulled back, until body
      weight is supported by partner one
      partner one does 1o squat lifts......

I didn't manage stretch number two beyond trying to get my partner onto my back as partner one, and my partner managing a couple of squats with difficulty due to my shifting body weight as partner two.  Am certain though that these two stretches are the guilty ones for this morning's aches 😊😊
