Why does this happen?

I´d check a doctor as well just to be shure everything is OK

Part of "the burn" you feel during repeated exercise is lactic acid (a waste product of metabolic processes), and part of it is the inhibiting chemicals.

Question - last night we did lots of leg conditioning. Lots of standing slightly crouched for the benefit of our quads, while moving forward with kicks, punches, etc. It really really started to burn after a while, to the point where I was making involuntary gasps and noises in pain. Then after around 15-20 minutes, I noticed that it was hurting less and I could stand it a bit more. Nothing had changed, we were still doing the same level of intensity.

What happened? Could my breathing perhaps have changed, or is it a mental thing, or did my legs suddenly become stronger? (as if, haha!). Any thoughts would be appreciated!

I believe it to be lactic acid working out for your benefit. I suggest to have someone massage the backs of your legs when you have finished the workout. Lay face down with your arms in front of you. Point the palms of your feet to the ceiling. Have someone hold your feet and let that person walk on the back of your legs, just like the way they made wine in the past. Then have that person cross your ankles and press your feet downwards into your backside.

Thanks for your response! Can you explain in further detail what you mean when you say the lactic acid is working in my benefit? That massage technique sounds like torture!

This massage for the back of the legs is nothing less than fantastic. The lactic acid is equivalent to nitro for a boost of speed for a car. Some athletes train themselves to use this to improve their performance. It is also associated with the afterburn effect, which is burning fat long after the exercises have ended.
