Hand cramping while serving

Since i've been trying to incorporate proper ESR into my serves, my racquet holding hand has begun cramping. I think its usually more on off-center or frame hits, or late etc. But it cramps really bad from my ring finger down to my palm. Its hard to hit the next shot sometimes because i have no grip strength, but it seems to resolve instantly (well 30 sec or so) if i stretch it out.

Any idea whats causing this? Is it just because i'm not used to hitting with proper ESR do you think?

The take-back constrains your hand. It is far from relaxed.

If you wanna go abruptly, check out Nole’s serve.

ESR - external shoulder rotation

ISR - internal shoulder rotation

These are defined joint motions and can be Googled.

The term 'pronation' is often used incorrectly for the serve but the actual significant motion is internal shoulder rotation of the shoulder joint. There is some forearm pronation also but it does not contribute much to racket head speed.

The shoulders do not move anywhere for ESR or ISR but the upper arm bone rotates around its long axis.

Can't see the connection with ESR other than it just exercising some pain centers of an already-present problem.

Would say forearm pronation is about as significant as ISR.

racket too much inline with forearm and not staying on edge long enough...closer to contact

ISR drives the long axis rotation and pronation when serving properly

just to add on to others comments...
OP is your over grip on the racquet worn? i change my overgrip (tourna mega tac - which is super tacky) just about every time i play, which allows me to keep my grip loose, yet still maintain a solid cohesion to the handle.
with a tacky grip i can hit fh & serves with my pinky hanging off the racquet (or 3 fingers even)

Pretty worn, yea I should change it. I use yonex super grap.

I have a feeling a lot of the cramp was due to the raonic serve style I was using though. When I noticed my racquet face was more closed than Salzy I dialled the raonic thing back... don't think it needs to be that closed lol (although it probably did help at the start so I had the feel down) @Curious

Whoa... sounds like your racquet arm, wrist, and hand are way too active for this move you're working on in your serve. Two thoughts:

First one is to try to repeat the move you're working toward in a smooth practice motion without serving a ball. Your arm and hand need to be loose and limber to generate decent racquet speed over the top and not actively steering or manipulating your racquet. If your hand is cramping, it's doing way too much work.

Alternate between taking a couple of smooth motions and hitting an actual practice serve. Get the actual serve to where it's as loose and smooth over the top as your practice motions. If there's any rush to the ball with your actual serve, consider getting a little more of your windup done before you toss the ball so that you're more ready to release to contact when the ball gets there.

Second one is to check your racquet's grip. I can get to squeezing too hard if there's not enough of a flare at the butt cap to hold it with relatively light pressure. I put either athletic tape or some extra overgrip on that flare to build it up a little bit, then cover that with a full overgrip.

Grip the racquet only tight enough to hang on to it. Keep your PALM DOWN throughout the backswing. Focus visually on the ball's surface and whip the racquet loosely at and through it, as if you were driving a nail with a weight on the end of a string, hitting the ball out of your visual field. Be wary of not taking the racquet back far enough, and, just before impact, (1) the instinctive tendency to "grab" the racquet, and (2) shifting your visual focus forward. If the serve doesn't have enough speed or power, swing it easier, not harder. This is how you serve in tennis.
