When you beat a guy, you need to accelerate around him with the ball under tight control, how can I learn to do this really well, I can already juggle pretty much forever. How can I improve those first 3 touches after you get around a guy so that you are in front of him and the only way he can get you is by fouling you?
Play a lot, concentrate, and, if you're alone, use cones and stuff in your yard. I used to have stuff set up all over my yard for this - a wheelbarrow, a tree, toy trucks, bicycles. We probably looked like we didn't take care of our yard much. ;p
Once you beat him, you do have to explode past him with the ball. However, think once I get past him I will immediately step into what would be the defenders lane of pursuit. So if he is on the right side of you you move to the right a step so now he is directly behind you then dribble. So now when you pass him he is then directly behind you. So he will have a hard time recovering and getting on your shoulder from that position. Try that, because if you just push the ball in front of you and try to out run him he can make a recovery run on you, and the back support player if he has good support position will beat you to the ball. A lot of balls are lost to that second defender as you beat the first guy. Oh, want to beat that second defender who has good support positioning also? After you beat the first defender while you still have close control move forward but in a diagonal direction left or right of the second defender depending on where the room to move is moving away from him. Move in a forward but diagonal direction you will beat the second defender as well. Practice it going one on one taking on two players the first then the second defender.
I dunno whether it is just a coincidence or not, but ever since i started toning my stomach muscles, I have increased on acceleration and dramatically on my pace as a whole. Try that.
A popular exercise from one of my coaches was 'steps/bleachers' (i.e. sprints up steps or bleachers) and them moving on to having someone pull you or dragging something (there is a term for this, but I cannot remember it right now) then he would blow a wistle intermitantly and the players would have to sprint several yards. All of this together generates strong muscles for the "takeoff" speed that is necessary.
I think sprint interval training is a good idea to consider. Here is a link with some information: http://www.elite-sports-training.com/intervaltraining.html
shorts sprints, as opposed to endurance training, would be best for this.. and do the sprints with and without the ball
