We have a growing number of exercise apparatuses that clutter our house, including our 2nd treadmill in 20 years that has pulled as much or more double-duty as a clothesline as the first one (how anyone who lives out in the country could want one of these behemoth contraptions cluttering up their house is beyond me, but wifey wanted so wifey got), and a rowing machine I really like that uses a turbine spinning in an actual tank of water as resistance.
We give this stuff away when we get tired of dusting it, and I really prefer walking out of doors where I can take advantage of 'forest bathing' and UV and infrared light therapy but my favorite, by far, is the cheap "rebounder," or mini trampoline that takes up about the space of a card table (unless it's stowed away on its side taking up less than half as much space). I just need to move it out onto my driveway, I guess.
I used to think these things were nothing more than the latest fad from 10-15 years ago until it was brought to my attention that NASA uses these things to build and and rebuild bone and muscle mass lost by astronauts on their zero-gravity working vacations.
I do a 30-minute HIIT (high intensity interval training) workout on this thing twice a day, six days a week that has me jumping up and down a whopping 1,728 times (think "sets" and "reps"—36 × 48) a day! Or 10,368 times a week, but who's counting? I don't know if all this is necessary and I'd cut back to just one 30-minute session per day if I didn't enjoy it so much. It also gives me something to do besides grow roots into my couch while I listen to audiobooks and sermons/lectures. Oh, and I was kinda hoping to become the first person in my family (so far as can be recalled) to live at least 100 years. I got a lot of stuff I need to get done.
I have an entire testimony about this little gem that goes back 47 years, when my doctor suspects I developed a crippling ailment that is now GONE, PRAISE THE LORD!!
