1. Working out blows.
After a quick sesh on the treadmill, you're sweating like you spent an hour in the sauna. Then there's the "Oh my gosh my muscles are on fire" pain. Add that to all the panting, and it's easy to see why a date with your TiVo is much more appealing.

Excuse buster: Don't be your own drill sergeant. There's no need to work those sexy legs of yours to the bone until the bitter end. Give yourself a good five-minute cool-down instead. Those last few minutes are what you'll remember most, so make them pleasant. That way, you'll be less likely to experience a dread-fest before your next workout.

2. I'm too busy to hit the gym.
This one's a toughie. We know being oh-so-fabulous eats away at your time.

Excuse buster: Don't take an all-or-nothing approach to staying fit. Don't have time for the gym? Squeeze in a 10-minute walk between work and that happy hour gabfest with your girls. Free yourself from getting ready for the gym duties. Instead of slipping into your gear, pulling your hair up and driving to the gym, just slide on your sneaks for a strut around the block.

3. I'll be the biggest girl on the treadmill.
Yes, there's a high probability that you'll stake your claim on one of those torture -- er, we mean running machines -- only to find yourself smack dab in the middle of a line-up of girls who look like they could be featured in the next Carmen Electra striptease workout video.

Excuse buster: Look around. Chances are you'll see someone as old as your grandmother, working it Sweatin' to the Oldies style. Just remember: Everyone starts somewhere. Ditch the pressure to use all those machines like a pro. Besides, a little birdie told us that you'll burn more calories when you're working extra hard to get those moves right. Bonus!
