At SobeyFitness, we don’t just train to “get sweaty” – we train with purpose, using data, science, and smart systems to build fitter, healthier bodies from the inside out.
One of the most powerful tools we’ve been using lately in our fitness sessions is telemetry training – real-time heart rate tracking that gives us instant insight into how hard our bodies are working, and how to push to the right level to improve fitness, not just exhaust ourselves.
And the results have been incredible.
🔬 Why OBLA Matters – and Why You Want to Train Above It
You’ve probably heard us mention OBLA during sessions. It stands for Onset of Blood Lactate Accumulation – the point during exercise where your body starts to accumulate lactate in the blood faster than it can clear it. In other words: it’s where things get uncomfortable.
For most people, OBLA kicks in at around 85–90% of your maximum heart rate.
This is a powerful place to train – but it’s also where most people back off.
But here’s the thing: training slightly above OBLA (with the right support and recovery) challenges your body to become more efficient. It adapts by:
✅ Increasing your aerobic capacity (VO₂ max)
✅ Improving your lactate clearance (so you fatigue less quickly)
✅ Boosting your metabolic flexibility (burning fat more efficiently)
✅ Strengthening your cardiovascular system
✅ Improving your mental resilience
This isn’t about redlining or punishing yourself – it’s about tapping into a training zone where real progress happens.
💡 Real Results from the Reboot Squad
One of our SobeyFitness legends recently showed just what this kind of training can do:
📍 Age: 47
📍 Predicted Max HR: 173 bpm
📍 Actual Max HR recorded: 193 bpm (equivalent to a fit 27-year-old!)
📍 Resting Heart Rate: 34 bpm
📍 Heart Rate Variability: 159 bpm
That’s not down to lucky genetics – that’s down to consistent, purposeful training. It’s what happens when someone puts their heart into it – literally.
🧠 Heart Rate Variability: The Hidden Health Hero
We talk a lot about Heart Rate Variability (HRV) at SobeyFitness – and for good reason.
HRV is the difference in time between each heartbeat. When your body is healthy, recovered, and resilient, your heart can speed up and slow down easily based on demand. That adaptability is a sign of a strong parasympathetic nervous system – the part of your body responsible for rest, recovery, digestion, and repair.
In simple terms:
💚 High HRV = Fit, well-recovered, adaptable, stress-resilient
❤️ Low HRV = Fatigued, overtrained, stressed, inflamed
Tracking HRV is one of the best ways to measure overall health – far beyond just weight or fitness level. A high HRV tells us your heart and nervous system are functioning well. And guess what?
You can train to improve your HRV – and that’s what we do in our sessions.
🏁 This Isn’t Just for Athletes
We know what you might be thinking:
“I’m not a pro athlete, so why does this matter to me?”
But here’s the truth:
Whether you’re 27 or 87, improving your heart health makes everything better.
💥 More energy
💥 Better sleep
💥 Less stress
💥 Improved weight management
💥 Lower risk of disease
💥 Better mood, brain function, and confidence
And that’s why we do what we do at SobeyFitness.
