Could Apple Watch soon track weightlifting as well as cardio?

As a fitness tracker, Apple Watch is currently little more than a fancy pedometer. It only tracks distance and calories — the quantity, not the quality, of your movement. That’s a problem because fitness is about more than burning calories.

However, an interesting patent from Apple — plus a new technology claimed to be “Siri for understanding human movement” — suggests that Apple Watch could soon be adding weightlifting to its repertoire. Which would be good news for gym-goers and CrossFitters everywhere.

Apple’s patents show they are thinking about weightlifting

In June 2014, Cupertino registered a patent for a “body-bar sensing system.” The patent described a special clip you attach to a barbell or dumbbell that communicates wirelessly with your wristwatch to automatically count your reps (the number of times you repeat a lifting motion).

Fast-forward three months, and Apple Watch was announced, with Apple placing fitness front and center as a key benefit. Weightlifting, however, was conspicuously absent.

Instead, like the FuelBand that Apple’s new fitness guru, Jay Blahnik, previously worked on for Nike, the new wearable focused entirely on running and other movement-based activities.

Weightlifting is good for everyone — not just bodybuilders

You might think the absence of weightlifting from Apple Watch is not a problem, especially if you associate that type of exercise with hulking Olympic athletes who grunt loudly as they hoist improbably large weights above their heads. That’s hardly Apple’s target audience, after all.

But the appeal of weightlifting is far broader than that. While running and cycling may still be popular with “MAMILs” (Middle-Aged Men in Lycra), a younger generation of fitness enthusiast are shunning endurance sports in favor of activities that focus on strength and aesthetic gains. In other words, lifting. Hence the growing appeal of sports like CrossFit.

The benefits of weightlifting are every bit as important as those of cardio. It helps increase strength and muscle mass, develop strong bones, control weight, boost stamina, manage chronic conditions and sharpen focus. So it’s not a question of doing either cardio or weightlifting — ideally you’d do some of both.

In other words, without weightlifting, there is an important component missing from Apple’s fitness offering.

If weightlifting is so important, why did Apple leave it out?

While cardio exercise is relatively easy to track using GPS sensors to measure how far an individual moves, weightlifting is much more complicated. You need to be able to identify exactly what exercise the user is performing, and the amount of weight they are lifting.

Currently, most gym-goers who track their weightlifting use an old-fashioned notebook or a gym-logging app like Reps & Sets (which I developed with my partner, Martin Algesten).

The problem with this approach is that you must log everything manually. Which is time-consuming and dull — meaning only the most dedicated weightlifters currently log their workouts.

Apple likes to provide simple solutions that are effortless to use. My guess is they are holding out on introducing support for weightlifting until they have found a truly elegant way of logging it.

The accelerometer in Apple Watch has untapped potential

Apple’s body-bar patent describes a clip containing an accelerometer that you attach to your weights. Since the Apple Watch has an accelerometer built in, this may no longer be necessary. The wearable could track your repetitions automatically, simply by monitoring the motion of your wrist.

This is not a new idea. FocusMotion is a Los Angeles startup that has created an SDK for developers, enabling them to build this kind of tracking into their apps. They describe it as “the Siri for understanding human movement.” While Siri uses the microphone to interpret your speech, FocusMotion uses the accelerometer to interpret your movement.

The company claims its SDK can not only count your reps, but even detect which exercise you are doing. So it can tell the difference between a press-up and a sit-up, simply by the motion of your wrist as you perform the exercise.

FocusMotion is currently available for Samsung Gear and Pebble, but the company promises support for more smartwatches soon. And with watchOS 2 allowing third-party developers access to the accelerometer, FocusMotion will presumably come to Apple Watch.

We haven’t yet seen what FocusMotion on Apple Watch can do. But if it is as good as it sounds, I think Apple should acquire it, and build the technology right into its fitness app.

This could be the missing ingredient that enables Apple to add weightlifting to their fitness ecosystem in their usual elegant and simple way — and without the need for extraneous accessories. If Apple doesn’t do it, third-party developers almost certainly will.

One day I hope I’ll be able to walk into the gym wearing my Apple Watch, complete my workout, and then, while I’m sipping a post-workout protein shake, review an automatically generated list of all the exercises I did, neatly displayed on my Apple Watch screen.

    Good article. As a user of Polar V800 I tried to use both at the same time and Apple Watch is way off when doing weight lifting. Polar V800 (using HRM) clocked the excercise as 900 calories but the Apple Watch was about 500. When using it to cycle or walk they are closer to each other.

    When using the Polar HRM with Apple Watch the weight lifting session goes alot higher in calories burned (more precise heart monitoring) telling me that the HRM in the Apple Watch does not “understand” strength training or calculates it wrong.

    Looking forward for Apple to fix this so I can use my beloved Apple Watch as my only watch but for now I am using Polar V800 for the gym.

    Good article. Slightly related, I wish my gym, LA Fitness, would WAKE UP and fix their Apple Watch app to facilitate using it for check in. It tries to work, but so far, it is WAY TOO slow! Also, PLEASE install free WiFi within the gym. If they would do this, for Apple Watch users who also have Blue Tooth headphones, one could leave her phone locked up within her locker and control music, phone calls, and notification alerts, all from ones wrist with just the Apple Watch. This will be SO handy and convenient. So the gym is the perfect venue for free WiFi!

      Can’t believe a fitness center without Wifi and it’s in a big city like LA.
      All 24 hr Fitness in Bay Area have free Wifi and also check-in process with finger print readers, 1 second check-in…Sorry LA, it’s not a Tech city.

      • Jared Porter says:

        Thanks for your info, maybe I should change over to 24-Hour Fitness, if they are being more tech/Apple Watch friendly? And actually I go to LA Fitness in Washington State.

    Look up Android wear vimofit.

    Apple hired away an engineer from the startup “Atlas Wearables”. They had a campaign on Indigogo for a watch that tracks weight lifting among other things. Their watch is expected sometime this year. Could they be acquired and their tech implemented into the Apple watch? I for one hope so.

  5. Les Tork says:

    Paying R300 pm at a gym to go and play with your fancy watch? Just lift dammit!

  6. Aannddyy says:

    Why is this necessary? I enjoy my Apple Watch, but a wearable tech has it’s limits. Can’t everybody just lift some weights till they are too tired?

  7. Krikaoli says:

    Let’s be honest, Apple Watch is not a good fitness tracker.. I can’t see my steps in real time, I can’t measure my sleep… And people like me who weight lift can’t use the Apple Watch at all… I put at the free exercise mode, but common…

  8. imtough says:

    Who the f*ck would use the link bracelet while lifting?

  9. Nick says:

    This sounds nice, but given the fact that the Apple Watch accelerometer can’t track standing consistently, I can’t imagine accurate rep counts, not to mention identifying which exercises are being performed, as being in the cards anytime soon. If they can get the movement tracking down, it’d be fine to select exercises you’ve entered previously such as squats, deadlifts, military press, etc. and then go at it.

    As mentioned though, the ability of the watch to identify that you’re standing and moving isn’t yet up to snuff. It works most of the time, but other times I’ve spent minutes standing, moving around, waving my arms etc. and it still won’t register. Accurately measuring one specific movement as one rep is hard to fathom at present. Maybe a software update can fix both the standing issue and the reps in the future, but given the centrality of “Activity” to the watch, I think they would have sorted this at launch or in the first update if they could.

    atlas seem to be the guys looking to nail this feature but I think it’ll be a while before any app will be able to automatically read the weight aswell as the exercise. Certainly it’s the way forward, bespoke personal training, integrated with something like i muscle that’s scanned your body, adjusting the intensity to your heart rate. I’m more interested in this side of the apple watch as a health device rather than all the notifications from text, social media etc which the phone is light years better at dealing with
