Great progress!! Always love to see the game grow and new players start up! Like everyone else just get those knees bent with a neutral spine, similar to how you would squat in a gym. All your power is going to come from your quads, hammies, and core. Always keep your core tight and engaged, it will help you keep your balance. Pads are a great idea as you'll become more fearless when out there, plus you'll need to get used to skating and moving with your gear on its vastly different. Start with the ski stop or 'pizza slice' motion for stopping, then slowly work on turning and using only one foot to stop. I find it easier if you're a left handed player to stop on you left, and vice versa for righties. Also use your arms. Swing them much like you would when running. It will help with balance, power, and speed.
