Improve Sprint Speed and Jump Height with Eccentric Overload
S&C coaches and physical therapists use flywheel devices to achieve eccentric overload in a save way.
Do you face following problems today?
No mobile device that fits in a regular airline suitcase that allows squat forces up to 250kg/550lbs.
No new training stimulus. Athleticism improvements have plateaued.
No save way of achieving eccentric overload.
No reliable way to measure the eccentric and concentric force at squats.
No eccentric overload in your work out at all, so you miss out on potential gains. Your muscles are naturally stronger in the eccentric phase, so why aren´t you training eccentric overload?
At traditional squats (with or without added gravity like kettlebells or barbells) you have concentric overload instead of eccentric overload which is contradictory to your natural muscle strength distribution.
If you say, yes that is my problem, to one or more of above points, you probably miss out on the benefits of flywheel training.
U.S. pro skier Brian McLaughlin performing explosive squats on the STREXBOX and we measured his forces with our Powermeter.
Brian performs his repetitions with 10% to 30% eccentric overload.

Why STREXBOX, there are in the meantime already other flywheel producers out there?
1) Flat box design due to horizontally mounted flywheel, US patented
- Less metal and powder coating costs for us which means lower purchasing price for you due to clever product design.
- Less storage cost in our warehouse which means lower purchasing price for you due to clever product design.
- Less shipping costs for us which means lower purchasing price for you due to clever product design.
- No pull belt gets stuck anymore
- Improved safety, in case you need to step off the platform it is just a small step
- Improved safety, no vertical flywheel you may accidentally touch or can fall onto and hurt yourself
- Any disadvantage is you have the flip the box to exchange the flywheels. In our view this one disadvantage outweighs above advantages 10x, or let´s be more realistic and say 3x : )
2) STREXBOX 24 x 16 inches = 60 x 40cm platform:
- < 4 inches/ 10cm high

- Detachable hip belt.
- Increased comfort and pulling power.
4) Powermeter Force Sensor
- Live force-time-chart for in depth analysis of the eccentric and concentric phase and live guidance of your athlete
5) Eccentric Overload Aid
- For professional S&C coaches only. Helps to further increase eccentric overload ability of flywheel devices
6) All parts fully exchangable

FAQ:
STREXBOX vs other flywheel producers
The main difference is that other flywheel producers have a vertical built in flywheel and we have a horizontal built in flywheel which we have US patented. Horizontal flywheel leads to more safety, larger movement area, device is easier to store, on the production side for us less material costs and less shipping costs which leads to a price advantage. Disadvantage of the horizontal flywheel: you have the flip the box to exchange the flywheels (if you change the flywheels often that may be important, if you don’t change it often above mentioned advantages outweigh this disadvantage from our perspective).
What is the difference between STREXBOX Home, Studio and PRO?
STREXBOX Home Set: Small Full Metal Box 60 x 40 x 10 cm = 24 x 16 x 4 inches, can carry up to 3pcs of L and XL inertia plates. Perfect for first time flywheel users who are looking for a competitive price as well as a portable and easy to store device.
STREXBOX Studio Set: same technology as used for the STREXBOX Home, but with a large standing platform 90 x 55 x 10 cm = 35 x 22 x 4 inches. Perfect for you when you need more space for sumo squats etc. Includes more accessories that are useful for professional studio clients, such as extension belts and bar for additional upper body workouts and more inertia plates for greater load variation. This device is able to fit a heel-up-and-lateral-squat-block due to it large standing platform.
STREXBOX PRO Set: same box as the STREXBOX Studio, but with additional tools which are essential for sport and conditioning coaches such as the Powermeter Force Sensor to measure the athlete´s performance and track progress. Size adjustable Pro Harness with detachable hip belt included which offers the most comfortable and effective workout gear for squats.
Should I buy a Box or Tower?
Box: best for squats and all exercises where you pull vertically
Tower: best for core, upper body. Basically if you want to perform other exercises then squats frequently the wall-mounted STREXBOX Tower is the best choice.
What is the max force I can achieve?
The resistance created depends on 2 factors:
- Amount and size of inertia plates
- Pulling speed, the faster you pull the more resistance
When an inertia plate says 0-60kg/0-132lbs, is that 60kg/132lbs of resistance?
Yes, that means you can achieve a max of 60kg/132lbs when you pull fast (with explosive squats for example to train jump height). The average force is below this value, usually around 30-50%.
That means when you squat with traditional weights 130kg/285lbs with 1 repetition maximum, you should look for an inertia plate load of around 260kg/570lbs, double the traditional weight load.
Therefore most people prefer 2pcs XL plates (2x120kg=240kg -> 2x260lbs=520lbs) for slow to medium pulling speed squats. If you want to do explosive squats, you usually reduce to 1XL or 1XL + 1 L plate, as the resistance of a flywheel device increases the faster you pull.
