In late 2022, Netflix added a range of Nike Training Club workouts to its library. You could access these for free (so long as you have a Netflix subscription) and do the 10 or 20-minute sessions wherever you are.
However, the partnership didn't last and the workouts were removed from Netflix in March 2024, according to What's on Netflix. The Netflix and Nike deal was meant to see if Netflix could compete with Peloton for streaming workouts, but it seems the company didn't want to progress any further.
Fortunately, many of these sessions are now available for free in the Nike Training Club app. But that's not to say Netflix will never offer free workouts again.
Around the same time as the streamer partnered with Netflix, it also developed a short series with meditation app Headspace, and the Headspace Guide to Meditation is currently still available on Netflix.
Of course, meditating alone won't boost your fitness, but it can be a stepping stone to low-impact activities like mindful walks, so it's another potential starting point if you're hoping to get into exercise for the first time in a while.
