Yeah. [0:01](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=1) And for the whole time, I want you to throw the ball with an overhand grip. [0:06](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=6) Oh, like this? Yep. Okay. So I want you to just throw it with the right arm and catch with the right arm. [0:12](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=12) Over... I mean, what's this one saying? Left-handed arm. [0:14](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=14) I'm just checking the wall. Okay. Okay, so catch it- Yep ... like this? [0:18](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=18) So you might wanna move back where the chair is. Okay, no, you're good. [0:22](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=22) Cut that. Cut that out. Good. So now throw with the right and catch with the left and alternate. [0:33](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=33) Yep. Oh, okay. [0:39](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=39) You've got it. So what we're doing, we're engaging almost all the executive functions now you've got. [0:45](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=45) Cut that out. And you should be able to do this for a minute. Okay? [0:48](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=48) Okay. Okay, so basically what you wanna do... [0:51](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=51) And if you do it with a black ball, it's actually, oh, even better. [0:57](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=57) So now we're gonna make it a bit hard and a bit neurally demanding. [1:01](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=61) We're gonna put an eye patch on you, which is really gonna block out like 50% of vision. [1:06](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=66) Okay. Which eye? Any eye. Let's do the left one. [1:10](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=70) Uh, let's see how many you can do. You... [1:12](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=72) I think you- we counted around eight before. [1:14](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=74) A pirate. Your eyes are gonna need to look good. [1:16](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=76) This feels significantly harder. I know. Let's go. [1:19](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=79) This feels... No, this feels like really hard. [1:20](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=80) Let me just double-check. Fucking hell. That's so hard. [1:24](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=84) This is- There you go. You've got it. Ha, joking. [1:30](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=90) Okay, let's alternate now. It's easier. Left hand, right hand. [1:34](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=94) Left hand, right hand, like this? Yeah. [1:37](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=97) You're training your visual system to work- ... under load and under stress. [1:44](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=104) You got it. You got it. You got it. Good. Good. Good. And then to even make it even harder- Mm-hmm ... okay, stand on your right foot. [1:52](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=112) Yeah. And put your other foot... There you go. [1:53](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=113) Standing on one leg is now engaging the cerebellum. [1:57](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=117) Okay. We're getting spatial awareness. Let's go. Posture. [2:00](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=120) Do left, right, left, right? Yep. Oh my gosh. [2:10](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=130) You got it. I wanna see you do it. With the eye patch on? [2:13](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=133) Yeah. Great. My eyelashes are gone now. It's okay. We can AI that out. [2:17](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=137) This actually looks great. Okay, are we ready? [2:23](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=143) Well, I blame my nails. I blame my nails. Let's do it. [2:27](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=147) Okay. It's hard. It's so hard. And so what is this doing? It's- This is engaging executive functions, processing speed, hand-eye coordination. [2:38](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=158) And you did this with NBA players? I did this with NBA players to improve, uh, their executive functions, decrease their reaction time. [2:46](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=166) This will change my brain if I do this frequently. [2:49](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=169) Not just that, but you're also improving cognitive reserve. [2:52](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=172) You're building new connections between the brain cells. [2:55](https://www.translate.mom/transcript/2lfDdiVkNaHk/en/tennis-ball-drills-for-hand-eye-coordination-and-cognitive-training?t=175) You're strengthening neural networks, and you're doing something incredible.
