Every little counts, especially if you make it a routine part of your day.
Even on days that I can't get a workout in, I'll throw a few pull-ups in on my bar just for good measure. Sometimes I'll do half a workout. Sometimes I'll just do a quick set before I leave the house.
Every little bit helps. No excuses not to move your body for a minute per day. You'd be surprised how far it goes.
Do you need to have an iphone back home for this to work? How does it play the music?
I've thought about smart watches, but i'd never wear it day to day, a used one isn't a bad proposition.
Yeah I think you'd need an iPhone for it to work. I think any smart watch would work fine though, just make sure that it can play music offline. For the apple watch I just tell it which albums to download to the watch then they're available to listen to even if it's not connected to my phone (or wifi).
I basically just use mine for running, the only other feature I like is that apple pay is slightly easier to pay from my watch vs pulling out my phone.
