hmmm...some interesting ideas here...thanks everybody
assuming you are a beginner "fightstudent" (arent we all beginners?)
try to learn only a few high probability sweeps (3-4) at a time. try to make them all from one position you find yourself in a lot (there are so many ways to play bjj nowadays)
for example: from closed guard, opponent down inside your closed guard - scissor sweep, elevator sweep, pendulum sweep. these are common sweeps and common names your instructor should be able to teach you these basic sweeps and some key variations in great detail. (if not, find someone that can)
first learn all the sweeps "by the numbers" or step by step. practice each 5-10 times or more if necessary sweeping to your strong side with a nonresisting cooperative training partner a little lighter than you. switch positions. learn the proper sequence and feel the technique.
sounds strange but try practicing reps with your eyes closed. this will help you feel the technique and timing.
second learn some realistic timing. have your instructor demonstrate variations of these basic sweeps and why you would choose to use these variations. there are ALWAYS variations and different possibilities. your instructor should know your game/level and what works best for your style and body type.
variations are any possibilities suited best for different situations, opponents body types, weight distribution, tendencies, styles, ect.
your instructor should have enough experience to be able to tell you what really works, when and why not just teach you techniques
lastly practice in live training against weaker players until you are successful with these sweeps with some regularity then move on to heavier/better opponents. here you will gain confidence with your sweeps and see the effectiveness of your practice and training.
eventually you will move into all the different sweeping positions and learn a few highly effective sweeps from each position, you will be able to sweep everyone you face and your teammates will begin to call you "sweepzilla"
just keep learning, practicing and training. good luck
i use these guidelines: (they seem to work ok for my students)
stay safe. be safe.
take it slow. no overnight ninjas in bjj.
learn everything step by step.
pay close attention to detail.
only perfect practice makes perfect.
be a good training partner. learn. teach. learn.
