Maybe I'm a little late here, but keeping on the topic, with a little work and with the help of the Free Stuff section, you can make fairly realistic muscular women. Here's a case in point. This started out as the standard Poser female, with Superhero morph set to .850. I then added the P4 bicep morphs which are available in Free Stuff (do a search for "muscles"). This download unzips into a large bicep and a small bicep, one for each arm. After adding the morphs to the model I set the Large Bicep morph to .333 and the Small Bicep morph to .100 for each arm. A little bit of airbrush was used in Paint Shop Pro to soften some of the joint lines. This isn't perfect, but it's the closest to defined biceps I've been able to get, outside of the generic Superhero morph. Comments welcome.
