Apologies if this was discussed before.
I see great progress with the stretch series - for example in just a couple of months I advanced in the pike from barely touching the ground with my fingertips to putting my palms down. BUT. This range of motion is only available after some warmup - my cold flexibility does not seem to have improved at all!
Is this normal, and how can I do better? I do daily limbering, but without it, I'm back to barely reaching the floor in the pike.
