Skate deck and two liter bottle of water. One legged squats and one legged Good mornings. Then move into balanced one legged weight training with dumbbells. Its all about the one legged shit. Get a BOSU ball, turn it upside, and do one legged bulgarian squats, good mornings, deadlifts, and squats on it with weight. I can get up to 60 on one leg, but its hard as hell to keep good balance for productive lifts. Practice without weight on a balance board first. If you can do 10 one legged squats in a row without falling, then your ready to move to weight. Anymore questions, pm me. I got all kinds of ideas.
