This is my gun of choice:
I'd recommend a massage gun for forearms and a lot of other muscles. Mine was a game changer honestly and mostly replaced foam rolling for me (no more rolling around on my legs all the time... just use the gun and watch tv). I have this one but there's tons on amazon
I own this one:
Renpho Powerful Portable Massage Gun, Quiet Deep Tissue Workout Gun Massager for Back Neck Percussion for Foot Massage, Muscle Massagers with 3200rpm Motor Rechargeable Battery Gifts https://www.amazon.com/dp/B085NTR26K/ref=cm_sw_r_apan_i_G6GD9FK6EG3G769628QZ?_encoding=UTF8&psc=1
And it's $75 with coupon right now. 100% worth it. I didn't believe these were actually good until a relative let me try theirs. It is actually great though
I have this and love it. The U-Shaped attachment is amazing for the shoulders and neck. Literally amazing. Also, the quality of the gun is ridiculously good for the price.

Serious question: those personal massagers, they sort of look like a gun, are they good for shoulder tension? My shoulder muscles are just one hard block of concrete. My legs are going that way too.
Do the personal massagers help or are those just decoy descriptions for dildos?
Here's a random one I just googled: https://www.amazon.de/-/en/Renpho-R3-Mini-Massage-Gun/dp/B085NTR26K/ref=sr_1_14?dchild=1&keywords=massagestab&psr=EY17&qid=1606410585&s=black-friday&sr=1-14
You can find them almost everywhere, got mine on Amazon Germany (this one to be specific: https://www.amazon.de/Massagepistole-RENPHO-Muskelmassageger%C3%A4-Massagek%C3%B6pfen-Schmerzlinderung/dp/B085NTR26K/)
