Not all resisted sprints are the same. Hill sprints create a natural horizontal resistance that teaches projection and front side mechanics. Chains and sleds overload horizontal force production, improving early acceleration. Resisted sprint devices let you dial in precise

4 reasons I use chain resisted sprints to train the 40 yard dash? 1️⃣ Teaches horizontal force production Forces athletes to push the turf instead of spinning their wheels. 2️⃣ Reinforces proper shin & body angles Chains punish early pop-up and reward correct drive-phase positions. 3️⃣ Self-regulating resistance Light early, heavier as velocity increases-matches true acceleration demands. 4️⃣ Improves first-step & 0–10 efficiency Targets the most important part of the 40: the start and projection phase.

5 Exercises for More Speed 1. Hill Sprints: Help you run in the correct form of acceleration and improve force application with each foot strike. 2. Flying Sprints: Teaches athletes to go faster and maintain maximal speed for a longer duration. 3. Heavy Sled Drags: Allow you to learn and practice acceleration mechanics at slower speeds. 4. Dynamic Skips: Improve knee drive, arm drive, posture, ground contact time, and rhythm - many factors that contribute to fast and explosive athletes. 5. Max-Effort Sprints with Complete Recovery: To run fast you need to do just that, run fast. Sprint intensity should be 95%+ on each sprint if you’re trying to get faster. Additionally, you need to be recovering fully following each sprint! Rest 60 sec. every 10 yards covered.

5 Exercises to Lower Your 60-Yard Dash ⏰ 1. Hill Sprints Hill sprints will help you run in the correct form of acceleration and improve force application with each foot strike. 2. Flying Sprints Great drill for developing max-velocity with athletes. This drill teaches athlete to go faster and maintain maximal speed for a longer duration. 3. Heavy Sled Drags Heavy sled drags allow you to learn and practice acceleration mechanics at slower speeds. To perform this exercise properly you need to posses a good forward body lean, and maintain a positive shin angle. 4. Dynamic Skips Skips are one of the BEST ways to improve knee drive, dynamic ankle stability, arm drive, posture, ground contact time, and rhythm - many factors that contribute to fast and explosive athletes. 5. Max-Effort Sprints with Complete Recovery To run fast you need to do just that, run fast. Sprint intensity should be 95%+ on each sprint if you’re trying to get faster.

Athleticism, the ability to move explosively and capacity to sprint are uncommon after 50, but that is merely due to a lack of maintaining those skills! There is a real possibility of injury but that can generally be minimized. There is a guarantee, not mere possibility, of decrepitude as we get older if we merely just let aging happen! Sprints tomorrow!

ICE had to force this chunky Juan out of the vehicle in Laguna Heights, Texas after he resisted arrest. A few oversized tortas lost their minds screaming, “What are you doing?! Let him go!!” Adios. No more free SNAP and EBT for your belly on the American taxpayer’s dime.

I hear some football staff say that in football important accelerations happen more in upright positions resembling more vmax mechanics, thus training should not prioritize starts from 0 velocity. For example, do flying accelerations mostly. Looking at one of the worlds best accelerators in football (Mbappe), you can definitely make a case that some key situations happen ALSO from good early acceleration mechanics. The shapes Mbappe gets into essentially reflect classic good 1-6 step shapes to beat his opponent: 1. Entire body orientates quickly into the desired direction in the sagittal plane 2. Most steps hit quite well under center of mass with good shin angles. 3. Pelvis stays relatively neutral so that there is force closer for good switching mechanics (both arms and legs). Seems there is some nice hip lock there too. These are arguably universal traits as ALTIS teaches. Yes, based on James Wilds model, you can be fast in different ways despite hitting these rules, but the point here is that the shapes he got into for success can highly resemble good EARLY acceleration mechanics. IMO, footballers need to be good at many things, classic early acceleration one of them. #startyoung

These are the same people who say we "block" roads! You can be sure that the Police and Electoral Commission "did not" and will not see this because, in their eyes, the law has a side and we're not on that side. This is why we need #ANewUgandaNow! #ProtestVote2026

If you’re not doing this, you’re losing power and stability in your swing. After a controlled load into the back hip, we have to be ready to unleash that stored energy into the ball. The only way to do this with both force and stability is by hitting against a strong front side — more specifically, our front heel. When we drive the front heel properly into the ground, it allows us to maximize both force and stability, enabling our mechanics to function correctly and generate gap-to-gap power! #softball #hitting #lesson

This is my fave acceleration drill, and it will NOT make you faster! ⛔️The classic wall drill doesn’t work. It just make your hips tired. Coaches around the world swear by them. We have all been doing them forever , because the angle mimics acceleration. When in all honesty, it’s just an inclined plank/hip flexor exercise. 💡So here’s what we reflected on💡 We asked … 🙋🏼‍♀️“what is a major output required in an acceleration?” 💡Well that had to be … “Horizontal Projection of your center of mass”.💡 Classic wall drill doesn’t have ANY hip projection. Horizontal body angles are the “EFFECT” of acceleration, but we wanted to have something that worked on the “CAUSE”? 🤨So what’s routed in the CAUSE? ✅Disciplined hip extension✅ 🙋‍♂️ What does that look like? 💡Shin discipline with trunk discipline allows one to utilise Lombards paradox💡 🙋🏿‍♂️What’s that ….? 💡Where the hamstrings & the quads contract TOGETHER rather than in an agonist -antagonist relationship💡 Said differently hip extension can result in knee extension, if the shin ceases to rise nore fall. ✅Co-contractions to maximise joint coupling✅ 💡Co-ordination and timing of triple joint extension is far more important than the completion of triple joint extension.💡 We have all been too concerned with the destination (full triple joint extension), without locking in on the journey ( joint coupling/coordination ) 🙋🏿‍♂️Will this drill make you faster? ⛔️Nope! No drill with low speed and low force will have Primary Transfer to sprinting. 💡But it will have Tertiary Transfer. Use the drill to feel efficient hip extension, with trunk and shin discipline.💡 📝Learn how it feels to have naughty knee roll,then how it feels to correct it. 📝Learn how your ankle stiffness allows for more explosive hip extension , how reactivity feeds your projection. ♻️Use this drill to create more space in your hips to hinge efficiently , setting the tone for prowler pushing , sled runs and acceleration work. TEACH in the gym and then ,TRAIN on the grass. Far simpler way to coach acceleration to team sports players. If you made it this far… Coaching Eye Quiz 👁️ Can you tell the difference between the start and end of the video? Jair Lee

Back in the 60s my father and his uncles fought the same old hateful rhetoric against immigrants and here I am some 50yrs later STILL fighting the same old rhetoric. Immigrants are not to blame for all societal ills. You are a racist if you think that and I will not change my mind about that

McKinney, Texas Resident Protesting the Islamic Mosque: “Muslims force their way into countries and force their religion. If you don’t accept their religion, they kill you— you may say not all of them are radicals or extreme, to that I say what book, what person, and what source does their behavior come from? The Quran and prophet Muhammad— so unless they condemn the Quran and prophet Muhammad, they are all the same. How can we not see this? I know you all sit up there, and your hands might be tied because there isn’t much you can do, after all these people are using our own constitution against us.. what I say to you is STAND! Do what is right! Let there be a lawsuit. Let us stand together knowing God is on our side.”

Ever heard of Connected Lenses on Spectacles ? Because together is more fun and this is a little glimpse into the future of AR. Connected Lenses let multiple people run the same Lens and share + save data across devices, whether you’re side by side or miles apart. That means you can build AR experiences your friends can jump into at the same time, then return to later, with the world still remembering what you all did.

🚨 LIBERALS ARE WAKING UP: “I RESISTED THIS FOR A LONG TIME…” 🚨 A former liberal openly admits: “I resisted for a long time the notion that Democrats were deliberately inviting masses of foreigners into the country because they wanted to grow little Democrats and create a one-party state.” “Before Trump closed the border, I thought a lot of it was incompetence. Now I think it was more intentional. The Biden administration opened that border on purpose and shipped people all over the country.” “They say we need young workers for Social Security and Medicare… but then they support family reunification, which means bringing in the parents. So much for improving the age structure.” Her conclusion: “There is design behind it… I don’t have any other theory aside from a pathological passion for minorities and a weird notion that non-white people are superior.” She ends with: “Folks are waking up by the masses, and it’s great to see.” Even lifelong liberals are starting to see the replacement agenda for what it is. The great awakening is happening. 🇺🇸

🇮🇷 LET'S DEBUNK A HUGE LIE! All over X people are ANGRY Iran's FM Dr. Abbas Araghchi for saying: "In the past, negotiations didn't lead to war. Resistance led to war." What people are leaving out is he is talking about how Iran RESISTED Trump's ridiculous demands and the U.S. attacked them and U.S. was defeated, in both the 12-day war and the 40-day war. He is not MOCKING resistance, or resisting. He goes on to talk about how Iran won, and how it is a SUPERPOWER NOW. This is why I TRANSLATE everything I post and hate 30 second clips. Context is KEY.

BREAKING: Trump just weighed in on Europe at the G7 Summit. "Europe has gone woke. Europe is not recognizable in many places." "You look at Hungary, Poland, Czech and Slovakia. They have gone very much the opposite." Trump drawing a clear line between Western Europe and Eastern Europe. - The same Eastern Europe that has been right about gold reserves. - The same Poland that vetoed EU censorship laws. - The same Hungary that has resisted EU regulation. The divide inside Europe is no longer subtle. It's being discussed at the G7.
