I don't really understand what this all means, because it seems slightly contradictory. Most bikini competitors, that I can think of, don't have a classic "hourglass figure" because an "hourglass figure" from my perspective still has relatively big hips and thighs (curves).
What's your current height, weight, and general bodyfat level (not a percentage, but an honest description - flat stomach, arm/shoulder definition, muffin top, etc.)?

35 minutes isn't much time to get a lot of work done, so you need to be really dialed in and focused. EDT is my first thought. That's the most simple way to get a thorough workout done while keeping a strict eye on the clock.
