I find technology does more to keep me UNFIT than fit. Thats just the opinion of a 47 yo who grew up playing in the woods on a 1000 acre farm hunting and fishing when you didnt have devices and apps to help you locate game or fish or tell you how many steps it is to your treestand. So that likely contributes to my not needing/wanting it now so if youre younger or just plain embrace technology no doubt you will have a different perspective.
But honestly, im going the opposite direction and decreasing my use of devices, particularly my smart phone, as I found that after experimenting with that sort of stuff the last 20 years or so i find technology to be more of a nuisance that distracts me from what i need to be focused on. If it werent for my wife id probably already be back to just having a landline in the house, no smartphone, so people can leave me a message when im at the gym or on my mountain bike keeping my fitness up and i can get back to them when its convenient for me.
