I am a huge fan of "hitting the wall" to practice your lacrosse stick skills. Great players, from the Powells to Paul Rabil to Steele Stanwick to Rob Pannell and many others have honed their craft by diligently throwing the lacrosse ball against the wall. Here are some items of advice for how to approach the "wall ball."
This list is posted over at LaxAllStars, along with some other GREAT advice:
FOR BEST RESULTS1. Find a flat brick or concrete wall at least 10 feet high, the longer the better
2. Every drill that you do- do it with both hands 50 times each!
3. Always wear gloves when you are performing your routine- you play with gloves so why not practice with gloves
4. Stand 5-7 yards away from the wall
5. Perform this routine at least 4-5 times per week
6. Each routine should be at least 20 minutes in length- if you finish all drills in less than 20 minutes, repeat drills starting with the drill that challenged you the most
7. Listening to music always helps me work harder, so crank up the tunes
8. Have fun!
