For gym shorts pocket carry, the Ruger LCP .380 will be the biggest firearm you will want to carry. It's doable, but still pretty heavy for draw string gym shorts. The Air-weight J frame and Ruger LCR .38 are completely out of the question. Not to mention the Ruger LCR grip is HUGE unless you find a boot grip or laser grips. The Ruger LCR in .357 mag is a fat heavy pig at 20 ounces when loaded - your shorts will probably fall down with one of those in your pocket.
Might even want to consider the North American Arms mini pocket revolver, if you can accept the small .22LR or .22 mag caliber.
Bubba's pretty much right. The LCP is 9.4 oz. A 642, 340, or LCR will run around 14 oz, give or take depending on model. A Kahr PM9 is 14 oz.
While running, weight is very important. The more it weighs and the more it moves, the more likely your pants are to come down. Something that may help would be a belly band type of holster.
I really, really do not like the LCP. Sights suck, trigger sucks, caliber is mediocre, recoil is brutal. BUT - it is one of the few guns that weigh less than 10 oz and carries more than two shots. For me, it would be a gun that I'd carry under very limited circumstances. It certainly has its niche.
If you know "gun people", you know someone with these guns. Swing by for pizza, and ask if you can job around the block with their pistol to see how it is.
