Who we are?

Speed4lifts was born out of the concern of two Spanish engineers, lovers of strength sports such as powerlifting, whose main objective is to cover the current needs in the world of strength training by presenting a unique and practical product capable of meeting and exceeding the expectations of other tools used by professionals in the sector.

What is a linear encoder?

A linear encoder is composed of an optical encoder capable of measuring angular movements and a coil that allows to linearize them, in this way, any linear movement can be measured.

For whom it is?

For every athlete and coach who is tired of erroneous methodologies and little current for the measurement of their training. For every athlete and coach open to using cutting-edge technology to start programming reliably based on the most important variable in strength training: THE EXECUTION VELOCITY.

How does it work?

Our encoder is a comfortable and simple device that is attached to the bar. Next to a totally free app that allows you to view and save data in an intuitive and efficient way.

What athletes need speed4lifts?

All those athletes with the need to quantify the accumulated fatigue, estimate their 1
RM and know the velocity of execution to carry out a reasoned and efficient programming
based on the last lines of scientific research.

How does speed4lifts serve me if I’m a personal coach?

For every athlete and coach that is tired of erroneous and current methodologies
for the measurement of your training. For every athlete and coach open to use
cutting edge technology to start programming reliably based on the variable
important in strength training: THE EXECUTION VELOCITY.
Offering an exclusive training to your clients is fundamental. Speed4lifts supposes the
best way to integrate personalization and technology for training professionals
as physical trainers either with orientation to high performance or prevention of

With which platform can I make measurements of the exercises?

Have scientific studies been carried out to ensure their validity?

Speed4lifts was compared with a main gold standard, the T-FORCE encoder. The results showed a reliability and spectacular validity.

It is of special interest to highlight the precision and reliability of Speed4lifts, since the maximum error is 0.46mm in the measurements and 0.0026 between the force-velocity curves.

What sports benefit from velocity training?

All sports have strength requirements to a greater or lesser extent. From a marathoner to a powerlifter, everyone must train strength. In the last alms, training based on velocity (by measuring velocity of execution) has proven to be the most current, efficient and correct training system for the programming of loads and determination of fatigue.

Does speed4lifts use kilograms or pounds?

Ambos. Puedes elegir la opción que más te guste, dentro de los ajustes de la app.

When I receive my encoder, what will I find in the packaging?
