Can SFQ active exercises replace regular aerobic exercise and weight training?
What I love most is that you can do the exercises standing, sitting, or lying down, so that if you're not feeling that great on a particular day, you can do them sitting or lying down.
I'm starting to experience electricity flowing through my body just like the manual said I would. Cool. My first benefit that I feel is a calmness. I'm more peaceful and I'm in a better mood in the morning. This is from only doing the active exercises for a few days so far. I'm trying to fit the meditation in my schedual too.
All I ever felt from Hatha Yoga was pain when I pulled something. I'm not disrespecting Yoga, I just did not feel any benefits from it other than some flexibility. Maybe one has to perform Hatha Yoga for many years to feel any gains. I feel gains from SFQ after a FEW DAYS practicing it. How amazing is that?
Master Lin is sure right when he says its' VERY powerful...!!
