I'm a big fan of agility ladder, hurdles, and cone work to improve foot quickness. But another tool I like to use is the slide board. It challenges you in the frontal plane which has a good carryover to most sports. It's a form of unilateral exercise. And finally, to be efficient at it you need to have a good initial burst step. The obstacles that most experience with the board is having access to one, or the fear of falling when trying to perform the slides. Well, get over your anxiety, and get on it! They're great, and provide a good challenge. Even if you're not training for the NFL combine, you can add a good aerobic workout to your routine. This is a nice change of pace exercise for a metabolic circuit. Again, give it a try, and let me know how it goes.
See you in the gym!
