Just remember that this website is completely public, which means any picture you post is out on the Internet FOREVER. There have even been cases of scam diet websites coming here and stealing members' progress photos to post on their own sites (and as you know, sometimes the "before" and "after" aren't the same person-- they might steal just your "before.") For your own protection, don't post anything that you might not want potential employers, coworkers, your (existing or future) kids, or potential in-laws' private detectives to find 15 years from now.
Even if you think you won't mind it being public, I would suggest that you put those pictures in your gallery rather than actually on your main SparkPage, and just mention them in your blog so friends who want to see can go look. That's safer; bots and spammers and image thieves don't generally look that deep.
However, as far as site policies go, I don't think you'd be breaking any rules. Women can post pictures in swimsuits or sport bras, so as long as you've clearly got your pants on, you should be fine.
I totally agree-- SURE!! I've seen a gazillion ads for fitness stuff where the guys are shirtless, with their 6 packs prominently displayed. And the girls all have on bikini tops or skimpy sports bras. It can be hard to really see the progress if it's all covered up with a t-shirt. And on the Biggest Loser, they always "strip down" for the weigh-ins.
