Today was my fourth or fifth time using the thigh abductors at the gym, and since I began, my inner thighs tremble. I found a similar question here, which has a good explanation of the different muscles used for stabilizing free weights, however it's not quite what I'm looking for.
This tremble is apparently a normal thing, but when I use the machine, I don't need to do all the balancing and stabilizing I would without a machine.
- Why does the tremble still happen?
- Is there any way to correct this or does my body just need to become accustomed?
I haven't noticed any tremble like this on any other weight types I try for the first time, so why is just my thighs? Also, leg adductors cause no tremble in my legs.
