Fitness Blender is my favorite free workout option. Their website lets you filter using tons of parameters: how many minutes, what body parts, intensity, equipment, etc.
Their "5-Day Workout Challenge for Busy People" is a great place to start getting in shape:
- 5 days of different workouts, meant to be done in order (I can easily loop them with a day of something else in between for a month without getting bored).
- 30 minutes including warm up and cool down.
- High Intensity Interval Training (which seems to be one of the best workout types).
- Genuine people who care about each other, struggling to do the workout with you, encouraging and guiding you throughout.
- Two levels of difficulty to follow along with, with adjustments so that you always have something for your current level and something to aspire to.
Tip for getting started: When I haven’t been working out for a while, it can be hard to motivate myself to jump right into something like HIIT, and I’m also legitimately worried about injuring myself. So instead, I’ll compromise and get myself started with something that I feel genuinely comfortable committing to every day so that I’m moving my body and getting a little sore in new places and am sort of reminded that I have a body(?) and then I’ll start with something more intense.
One reliable place to start is the 3-day Flexibility Challenge (which you can also run on a loop as you ramp up):
Improving my range of motion will help prepare me for more intense workouts, but these are also (secretly) strengthening exercises that will help with stabilizing muscles to reduce odds of injury.
You can also use the entire library of videos and just filter for something relatively quick and easy.
