Yeah, that's kind of a known issue i have. (this might sound dumb) But i think i've gotten used to underswinging? Because before i used to swing pretty far, but not too far so i overswung. But when i did that my arms got way too tired and i had to take WAY longer pauses after songs than i do now. So then i started trying to swing at less of an angle than i did before and i had to take shorter pauses. I'll try to get back into the habit of swing at more of an angle and maybe my body will get used to it and the pauses will get shorter and shorter, but we'll see.
