Despite the unfortunate name (don't yell this one across the gym floor!), the snatch is a powerful total-body move.
Grab a kettlebell in one hand with an overhand grip. Squat down until the kettlebell is centered between your feet, your arm straight. In a single movement, snap your hips forward and stand up as you try to throw the kettlebell at the ceiling—without letting go of it. Allow your forearm to rotate until your arm is straight and the kettlebell flips over and rests (gently now!) on your forearm. For more of a challenge, use a 'bell in each hand.
Form tip: Keep the 'bell as close to your body as possible at all times. Good form is important so if you're confused, check out this video.
