Cool. That's what the game is all about: working on a new skill for a week until you're better. You'll be amazed at how quickly you'll improve at this.
A few tips for anyone struggling with this:
#1 --> lower your seat as much as possible (unless you're using a BMX or DJ bike).
#2 --> One common mistake with manuals is that people lean their head forward towards their bars while pulling up. You don't want to do that, you'll never find your balance point. Watch my head in the video. It goes back, not forward. It's all in the hips. You want to shift your butt/hips back away from the bars so you're balancing over the rear axle. Think of your bike and body as a giant teeter totter that's pivoting on the rear axle. That'll help you realize how much weight you need behind the rear axle.
#3 --> don't lift the wheel by bending your elbows (like a pull-up). To do it correctly, you'll be pretty close to locking your elbows and arms straight so you have room to get your butt behind the rear axle (like a push-up, only you're pushing your body back).
You'll still initiate the manual with your arms, but you'll be doing it by shifting back, rather than bending your arms toward your chest. You'll keep the front end up with your weight transfer to the rear. Pulling up this way, it's next to impossible for beginners to loop out. You REALLY have to get back there to loop out. And if you do start to loop out, tap your rear brake, or hop off and land on your feet.
As Lee McCormack would say, "heavy feet, light hands."
