I've got some old DVDs from Jillian Michaels and stuff like that lying around. My girlfriend says that's totally outdated and I should watch YouTube videos instead. But doesn't the training still work just as well as it did back then?
DVD videos work just as well physiologically as they did back then - whether you do a burpee in 2004 or 2026, your body reacts the same way. The advantage of YouTube is more practical: you've got unlimited selection, can switch things up quickly if something doesn't work for you, and it's free instead of being stuck with old discs.
The training itself works just as well as it did back then - the exercises haven't suddenly become ineffective just because the DVD is older. What's changed is more the availability and flexibility: on YouTube you'll find thousands of free options, you can pause whenever you want without having to dig out the DVD, and these days there are trainers who've incorporated newer knowledge (better form cues, less injury risk and stuff like that). If you enjoy working out with the Jillian Michaels DVDs and do them regularly, I'd just stick with them - consistency matters more than whether the videos are from 2010 or 2024. But try a YouTube video sometime too, maybe you'll like that format better.
The physical strain stays exactly the same - a burpee is a burpee, whether you do it in 1995 or today! Your body doesn't know the difference between a DVD from back then and a YouTube video. I've still got old workout videos at home, and honestly, when I dig them out, I don't notice any difference compared to newer stuff. The next day is just as sore!
But the practical side of things definitely matters - and your friend has a point there. YouTube just gives you incredibly more flexibility. You can pause, skip ahead, rewatch a part without having to start the DVD over. And if a video doesn't work for you, hundreds of alternatives are just a click away instead of being stuck with one trainer. Plus, newer videos sometimes take newer findings about joint care and stuff into account, even if the basic movement patterns stay similar.
My tip? Keep using the DVDs if you like the program and it works for you! But for the future, I'd also suggest exploring YouTube - not because the old stuff suddenly got bad, but because you can train more flexibly that way and don't always need the same trainer.
