Track Your Strength with Precision

Tracking your fitness progress is essential, but measuring strength in functional training can be challenging. Traditional gym machines make it easy with built-in metrics, but functional training tools like ropes and bands lack this simplicity. That’s where our lineup of strength sensors comes in. These portable devices deliver accurate, real-time data, making strength testing simple and accessible anywhere.

Why Strength Testing Was Traditionally Easier with Machines

Traditional gym machines have long been the gold standard for strength testing. With fixed weights and digital readouts, they tell you exactly what you’ve lifted - no guesswork required. Functional training, on the other hand, involves dynamic, free-form movements that are tougher to measure without the right tools. Our strength sensors change that, bringing precision to your workouts without tying you to a machine.

Why Strength Testing Is Key to Any Training Regime

Strength testing isn’t just a nice-to-have - it’s the foundation of effective training. Here’s why it matters:

  • Set baselines: Knowing your starting point lets you measure real progress over time.
  • Track improvements: See how your strength grows, week by week, to stay motivated.
  • Prevent injuries: Spot weaknesses early and adjust your routine to avoid strain or overtraining.

Tailor your workouts: Use precise data to target specific muscle groups or movements.

Beyond that, strength testing helps you optimize your training regime. Whether you’re building power for sports, improving endurance, or rehabbing an injury, accurate measurements let you adjust intensity and volume to match your goals. Without this data, you’re guessing - and that can stall progress or lead to plateaus. Our sensors give you the numbers you need to train smarter, ensuring every rep counts toward your bigger picture.

Why Powrlink® Strength Sensors?

Graphical live feedback

For the first time, you can make complex functional movements measurable and adjust your training accordingly.

powrlink Sensors measure every movement and show you the current resistance and your overall workload in easily understandable numbers and a live graph. Invaluable information will be right at your fingertips.

In-depth analysis

The resistance curve of every rep will show you how you are performing the exercise.

  • Is it very steep? Maybe you should perform each rep slower.
  • Do the peaks not reach the same height later in the workout? Then you are not producing as much force.

powrlink Sensors give you information that probably no other device can.

Complete history of every rep, set, workout

Compare youself against your previous efforts and see how far behind (or ahead) you are from your personal best.

After the workout you can deep dive into analysis of every repetition of every set. Compare the peak resistance of your exercises and your total workload across the whole training session.

Machine or Functional Training? We’ve got you covered.

powrlink Sensors can be used with a wide variety of fitness equipment. Hook it in-between your suspension fitness device and the anchor point, connect it to a resistance band, use it on a rower or cable tower. powrlink Sensors are as plug-and-play as it gets!

Use our sensors anywhere and with many fitness devices like Slingtrainers, Cable Towers, Rowers, Rope Trainers, Powerbands or Eccentric Trainers!
