ā¼ļø Endless tap dancing drills is NOT what is going to turn you into the shifty athlete you want to be
Do I touch on this often? Absolutely! Why? Because it is something athletes, coaches & parents need to keep hearing
Iām not saying some ladder work or basic cone drills canāt be a warm-up. Iām not saying they canāt have the benefit of coordination and some rhythm
Quick contacts can ALSO have force output benefit much like skips, pogo jumps and the like. The issue is: Iām not out there saying pogo jumps are the key to being able to change direction & cut at a high levelā¦
But many are still out there saying that throwing a ladder down on turf of dancing around cones for 15-20 seconds at a time with your head down are major needle movers for change of direction
Lastly (when it comes to ladders or cones). They CAN be done quite well for intent driven footwork, but they often are not
To me, these 6 things are the key to building & training change of direction or even agility
Save them, program them & level up your training!

What athletes THINK is going to keep them healthy is often far different from what ACTUALLY keeps them healthy
Quality strength + speed training is 15x more likely to keep you from suffering an injury than just stretching alone
More heavy lifting is far less likely to get you hurt than playing 300 games per season
& if you ONLY train in the off season or pre season⦠good luck!

āļø I love seeing STAR pro athletes who do quality training & emphasize what young athletes should focus on DOMINATE
Bijan Robinson put on an absolute show tonight & watching his speed, power & movement was a treat
Bijan shows young athletes that being bigger, stronger & faster & hammering basics like quality lifts & sprints is the way to go
I know he has elite genetics, but to me that just further drives home the point. Even HE gets better hammering fundamentals with intent
Also, (no jinx) he has not missed one single game in his young NFL career so far as heās 3 games into his 4th season. That is quite impressive and a telltale sign of a strong, well prepared body
Kids: learn from the elite & trust that quality fundamentals & emphasis on the weight room, intent driven sprinting & jumping will pay off!!

š„ Why you need to be utilizing contrast training in your training program!
Have you ever heard of contrast training? The idea of doing a more resistance/maximal force output exercise BEFORE a speed, jump or ballistic movement?
Itās not a NEW concept (been done for decades) but it is one many athletes do not take advantage of
The idea is simple: the resistance exercise is done as a form of post activation potentiation⦠the concept that the resistance or maximal force output exercise gets you to recruit a lot of muscle fibers and then you parlay that into enhancing your speed movement!
The goal should be to make the two movement patterns similar (as you can see in these pairings)
Rest can vary, but we like to do 30 seconds between the two exercises and then a full 3-4 minute rest between sets!
Show a friend who wants to build big time speed or power!

If you still believe ANY of these things, you need a big rude awakening and education!!
Lifting in-season doesnāt get you hurt! Poor lifts with bad form or poorly executed lifts will get you hurt. Lifting (correctly) will keep you healthier!
Not training in-season just completely gives back all the gains you made the entire off season. Itās one of the WORST things you can do
