I have just opened an account because the other day I read an article here where some coaches showed what tools they are actually using in the gym. Christian Thibaudeau has a tool called Vitruve that seems to be used for tracking the barbell speed in the gym.
Even If I don’t compete in powerlifting, I take it pretty seriously and wanted to know if any of you have any experience with it.
My idea would be to use it for estimating my one rep max and for getting real-time feedback so I can lift with more intent.
Thanks in advance for your answers!
I can’t speak to using this tool for your 1RM but i can confidently say the best way to estimate your 1RM is to lift it.
Most 1RM estimations are incorrect IME. I did think this tool was quite interesting when i read about it though.
The device actually approximates the max by using velocity and weight. While it varies individually (the prediction might not be accurate for everyone) it does allow you to track strength progression without testing your max.
What happens is that your speed should be dependant on the percentage you are lifitng. for example, you can lift 60% faster than 80%. There are averages regarding how fast the bar will move at various % of your max.
Granted this is individual which is why you can’t use velocity-based 1RM prediction unless you test ans athletes own strength-velocity curve.
HOWEVER you can evaluate progression this way. If you do 400lbs x 5 at an average speed of 0.7m/s and then do 400lbs x 5 at an average of 0.82m/s you got stronger.
The method makes sense for sure. Is it a “strength curve” or is it more linear when estimating 1RM in your experience?
Sorry, nerding out a bit and interested if there’s a particular equation that is commonly used
