As a running coach, not a PT, when I suggest strength work to clients I give them a link to an online workout. I know the time and effort that goes in to:
looking in to the work of people offering workouts, curating which are worth following and which are not,
workouts at the right level for current fitness and abilities,
workouts of the right duration,
workouts matched to current injuries/niggles/weaknesses,
providing links cued to the exact point to start.
What I look for in a YouTuber and their workouts:
follow alongs with no time wasting, self promotion, or advertisements in the middle,
down to Earth, knowledgeable practitioners passionate about their work,
concise video formats that don't waste time,
production quality good enough that the moves can be seen clearly to help execute them correctly.
I've seen a lot of fantastic and wanting videos, and over time I've developed a list of 'go to' YouTubers:
Vlad Ixel is an elite runner and has great videos about strength and form for trail runners. His videos are just enough to give a workout, while being short enough to feel easy to fit in to a busy day. His work on stability is particularly great. Friendly, down to Earth, does his videos as follow alongs, and has audible timers. You often have to skip some preamble, but he has the workout length in the video title so you know what you're in for. Try out some strength and stability.
Tom Merrick has a calisthentics focus, but he has full strength, flexibility, and mobility workouts that are fantastic for runners. Some of them target areas, while some are whole body, so you can choose the level you need. He has a warm, friendly approach, and does his videos as follow alongs. He also has an app with lots of his work easily accessible on there. Try out a hip mobility workout.
Caroline Girvan is also an ultra runner, and she has a huge range of strength workouts, lots of them with dumbells. She posts series of follow along routines that have professional production value: countdown timer, audible timer, what's next inset, how much time is left bar, and other great features. One of the best things is she doesn't talk! You can crank up her great music and get it done. Have a go at one of her core workouts; ten minutes never felt so long!
Sally McRae is an elite ultra runner who vlogs a lot of her race preparation, resulting in some great videos of her workouts. For proper follow alongs, you'll need to get her Choose Strong app which costs, but you get a 7 day free trial. There are some great routines on there, with detailed instructions and videos demonstrating how. Also, if you pay for the app you don't just get Sally's routines, you get access to anyone else on the Playbook app which is pretty cool.
Meg Takacs is a running coach with fantastic short videos on how to get your body strong, mobile, and moving in a way to prevent injury. She's shifted off of YouTube and you can find her most recent content on Instagram at meg_takacs.They aren't follow alongs, but she gives a clear view of how to do the moves and explains their importance.
Guerilla Zen Fitness is fantastic for corrective exercises to help with your functional fitness. There's a huge library of videos covering all kinds of biomechanical issues. He does the moves with you, providing detailed explanations of the move and the reasons for it. He also seems to have shifted off of YouTube on to Instagram at guerillazen. Have a log at stretching your hip flexors with him.
So there are some of my favourites! I hope you find some great routines to help you with your running.
Hope you enjoy,
Beck xx
