How much time to raise energy in legs?

[andonitxo]

Hello,
I found accidentally this web and during the last 2 months I've been practicing the exercises explained in NEW system.
My question comes because I last about 1 hour to raise energy in my legs, which is a lot of time for my horary.
With my arms the exercise goes very quickly, and I feel more energy related sensations.
When exercising my legs should I go on unless I don't feel so much energy not to get stagnated in them for hours?
Thanks in advance for your help.
Ah, my dream recall have increased very very much.
Greetings.
