Hill starts
Another thing that helped me was learning not to pull on the handlebars when starting out. Try to keep a very light grip and generate the power with your legs and push back into the seat. I found this got harder when I reclined my seat more on the Corsa. The more reclined your seat the less support you have to push against. It's also good practice when riding uphill to ride with just one hand on the bars. It reinforces the light grip method. I agree with Grumpybear's comments; practice a lot and those uphill starts will become second nature.
