Subconscious Tensing in the Muscles?

[Degekozen]

I've been attempting to consciously astral project for about a month a now (None so far but I am not losing hope!) and I've noticed a trend in my latest attempts that may be thwarting my state of sleep paralysis...

My muscles (mainly in my arms and legs) will subconsciously tense, but only slightly enough for me to notice after a few minutes that they have and that I could re-reach my relaxed state. Now the problem is that this will occur constantly and as if only a few moments have passed after I relaxed said muscles and they will, once again, revert to this slight tensing.

Why is this happening?
How can I prevent this?
(Bonus Q:) How do you "move" your astral limbs? E.G. For correct use of the rope, roll-out, push/pull, etc. techniques?

I get that, when I was meditating in the lotus position earlier today I noticed how every-time I felt a mass load of energy, my leg would tense which distracted me. I'm not sure what it is, but I knew it was something to do with discomfort.

Precisely. Usually around or just right before the vibrational stage I would notice my limbs becoming increasingly tensed. I'm being as passive as possible mentally, but I guess my physical body reacts adversely to the bursts of energy.

What position are you doing it in?

[Degekozen]

Well, most of the time I lay down in the basic prone position on my back, but on some days ill try to mix it up and lay flat on my stomach in a position that I would normally be sleeping in.

In most night attempts I find a lot of my muscles tense up like crazy if I attempt for a prolonged period of time.
It happens kind of without my knowledge too. Its usually occirs when I get really deep into a F12 and attempting a projection. I would relate it to picking up a cat by its scruff. The whole body kinda tenses up.

I would say, don't do night attempts. I have never tensed up doing drowsy attempts.

Cheers,

In another forum, someone posted that I should stretch the muscles I use the most thought the day as they tend to tense through meditation. Seems plausible as I'm a cashier at Publix, so I do have my legs, arms, and hands tense throughout the day.
