Is the 10 min workout included in the app considered a cardio workout or a mix of cardio and strength training.

I'm not a premium member, so I don't know, but you'll know it has strength training in there if your muscles are specifically being worked on. If it's just cardio movements that use a bit of muscle, it's just cardio.

I think it’s meant to be whatever you want it to be. The point is to do something in this 10 minutes so you can build the habit of exercising. After building the habit you start to increase the time you spend exercising. At least this is how I understood it.

Do we care? 🙄 Haha
I mean, do what works for you!
Where I'm at now in the app, u have a morning exercise which for me is yoga, and another one at night which for me is either a workout from my program (mainly strength, and a little slight bit of cardio) or my rugby training twice a week. On the weekend, this night exercising session is my weekly 1 hour run. Do what's best for you! If you do some heavy lifting you can't be doing that everyday, so maybe one day strength, one day cardio, one day bodyweight,… The important is to do something and build the habit!

It's a mini-HIIT (High Intensity Interval Training), so by design the exercises are supposed to give you the best of both worlds 🙂 you can do some of them with weights, if you want – for added benefit.

I am sorry I have not tried the workout in the app. However, any activity that gets your heart rate up is cardio. I personally don’t worry too much about those labels. I just try to move the needle by moving more and now doing some kind of formal exercise every day. I am learning that doing a short workout everyday is better that doing a killer workout and then being too sore to do anything fir a few days.
