I have to disagree with some of this advice. She offers enough 'instant satisfaction things' here you can get before you get to know her vibe and style - flashes, spanks, prize wheel, dancing, doggy style ass view. That gives you a lot of options. The only other thing to add would be more maybe nipple twists or nipple clamps.
She's on MFC and MFC is heavily based off chatting, interaction, and a model's unique personality and talents. Personality is prime currency for a model on MFC, not in every room but the vast majority of successful ones. You might find other cam girls personality a wall and that's fine - those rooms aren't for you. I'm not into girls who _____, _____, or _____.... but sure as hell a lot of people are.
Holly, If part of your personality is exercise that's rad and members will respond to that - use that to your advantage to interest people where that's their thing. Workout shows aren't for everyone, but don't throw all your goods out at once (meaning combine vibes with workout stuff in one tip) in an effort to entice more tippers - more than likely this will exhaust you and backfire. If they want to add a tip vibe to your squats or push ups - great (checked out your current profile) -- but I'd ask extra for it as an '+add on' or make it a once a week special or a specific countdown. You might not get a ton of people into this at first but the right folks will dig it. It's always a balancing act to have members stay engaged in your room, while maintaining your excitement and spirit while entertaining. If members are having their fantasy killed because you look too much like any lass at the gym, or changing your clothes, and they're not helping towards your goals then good riddance with them. You'll make plenty of customers happy.
You can't please everyone and don't try, they'll zap you of your energy.
Also...
Instead of making this a tip menu item you could make a challenge out of it for a fashion show or a workout clothes show - say "I'll put this timer up for 3 minutes and if we can get 20 tips of X - then we'll do a quick costume change." Who is to say you can't make the act of changing it's own mini-show, ppfffttt what downtime? A tip challenge is a fun way the room can decide their own adventure, by those who actually are participating... orrrrr you can put this up for a larger tip amount on your menu. I would say a good number to start with is 600 or more but honestly the larger the number the better.
