Static contraction burn?

[Fender]

Normally, after a weightlifting session, I feel my muscles burning and tired (not in pain though).

But recently, i have tried static contraction. I absolutely pushed my limits and hekd the thing in place for 8 seconds. Sometimes, my face looked like some contorted clay putty. But anyways, when I step out of the gym, i feel tired, but no burning sensation.

Does this mean I'm not doing the static contraction properly?

Thx.

Don't go by feel, go by weight. If the weight goes up then you are doing it right.

Just stick to the basics, lift more iron.
