🤔 Why are so many athletes underdeveloped, undertrained & getting hurt? Let’s talk about it!
I’m not saying this is the ONLY reason but I do believe it plays a big role. Athletes play their sport almost year round now, will only strength train in a 2-3 month “off-season,” window and wonder where things go wrong
You need to be working to get strong all year. You need to make sure your body is strong, stable & resilient. These are necessities if you want to give yourself the best chance to be healthy!

‼️ If you want to get better as an athlete… this list is a good place to start!
First & foremost, I can’t tell you how much better you can get by sprinting, jumping & lifting with intent 3-4x consistently all year
Amplify that even further by training to be an athlete and doing all of those things unilaterally and in various planes of motion
Fuel your body with proper protein intake & one of the most studied & effective supplements out there (creatine monohydrate) and BOOM… GAINS (as always consult with a registered dietician 😊)
Go get your gains!

Hip flexors are key to speed development… try this exercise!

Gave these a try today. We liked them, thought you might too

End of a speed day accessory

So much accessory “hip flexor,” work is focused on concentric pulling into flexion

What about eccentric forces into extension?

Rapid pull/lift. Let knee free fall

Catch & control

Drop jumps vs. Depth Jumps. So many misunderstand & incorrectly use them… Let’s talk about it!

Both involve the idea of falling from a raised surface, making ground contact & moving into a subsequent jump

However, they are VERY different in terms of what they accomplish & why we should use them!

Drop Jumps:

- Smaller drop height/GCT
- < knee bend
- Maximize output relative to momentum
- Helpful for elastic contacts

Depth Jumps:

- Higher drop height/GCT
- > knee bend
- Maximize output via big collision
- Helpful for peak output

👀 Curious what an early off-season lower body day looks like? Go through one with us!
The main premise here is foundation. Preparing the body and limbs for higher impacts we will experience later on
We are utilizing higher reps with lower intensities to accumulate overall workload that we can use to our advantage once we move to higher intensities later. You’ll notice constant themes of isometric holds to remove the rapid stretch reflex on loading, isometric holds on landings to stabilize & solidify positions etc.
You will also notice a lot of eccentric tempos on our strength work for the same reasons. Time under tension to accumulate metabolic stresses & stimulate growth… here are the exercises
1. Band distracted front foot elevated split squat
2. SL RDL on air-ex pad
3. Elevated 90/90 with med ball
4. Bilateral rhythmic lateral line hops
5. Unilateral rhythmic lateral line hops
6. Rope walks
7. Two point stance sprints
8. Band accelerated SL broad jump with stick
9. Med ball split stance jumps with stick
10. Extensive depth landings
11. Seated box jumps with med ball
12. Extensive frog jumps
13. Eccentric focused barbell back squats
14. Incline KB RDL
15. Front foot elevated split squat
16. Physio ball abdominal rotations
17. Physio ball hamstring curls (eccentric only)
