I think it would be kind of fun depending on the diaper. Also if it was a pull up style or a tape style of diaper, I think the pull up one would be better, I would be afraid of the sides opening on the other.
I have worn beneath cotton running pants (with drawstring) when I was in college. Just walking to the club location on campus about 1 mile away was enough to bother me with the padding between my legs. I would defintely not run in them. Also, I could feel the cotton jogging pants slipping on my plastic underpants and was thankful I had a tight drawstring. Add in the overall bulk and I was happy the jogging pants were a bit large in the butt (though I still felt self-conscious that someone might hear the sound when I was moving). I lifted some weights but just felt uncomfortable doing any exercise from the waist down. Having people know I wore protection at night for security reasons is one thing; having them find out I sometimes liked to wear during the day also would definitley bother some people that can understand the bedding protection but not the enjoyment. But this is just my opinion.
I do mon, wed, and Friday. I have to due to my OAB. I would not get through a workout without going several times. If your not use to it, yes it's uncomfortable. I wear the Biancos from Bambino. It took me time to get use to it and skin to get use to the rashes, which I don't get anymore. All is great now! I'm sure people even see my diaper once in a while if my shirt pulls up, but I try to do a good job of hiding it!
No one really cares. They may look out of curiosity. It's a good topic of discussion if someone is curious. I know people have seen mine and look but don't care. I don't care, I'm too focused at the gym. If they say something I would tell them it has been a life long medical condition.
I've never done it, and i've always wanted to ~ but living in Miami makes it especially difficult and uncomfortable; for one, its WAY TOO HOT to simply wear a diaper on a NORMAL day, let alone when your body is getting warmed up and being pushed to sweat ~ The diaper becomes uncomfortable, you chafe, it actually makes you FEEL hotter and sweat MORE. Though I've wanted to wear during yoga, but even this presents a problem with the balance of your body. I wouldn't mind lifting weights or using a machine while working out and wearing, but as far as using my body weight as a work out, or running, or squatting or really anything in which my body is in constant motion ~ I wouldn't recommend it.... at least not where i live lol.
That and another thing about not wearing in yoga is the crinkle lol, i dont care if my diaper shows or if people see it, but the crinkle would make the calm and silent vibe of the room pretty awkward.... its not so much that i dont want people to know im wearing, i just dont want to be "that person with the Sun Chips bag in a library" if you get the reference xD
Well, I run either with a Abena M4 disposable, or a Depedeco AIO. I've found that it's best to forgo the plastic pants, as they are the major cause of the chafing. Also, I would wear when I was running slower, (with my dog) and wearing because I like how they feel. If I was wearing out of necessity, a slimmer diaper, and some barrier cream would help limit the chafing. Where the diaper rubs my thighs was always the problem.
We runners are way ahead on this topic! I wear Depends Maximum Protection when I'm running, usually about six miles a day. They're also fine for longer runs. Several years ago I ran a marathon while diapered and had no problems, not to mention all the training and long runs leading up to the race day.
Before my recent weekday purge I did my morning exercises, (sit ups, push ups pull ups stretches etc.), in whatever I woke up in and in whatever condition it may have been in every day. Now I'm diapered on weekends but still go through my morning routine diapered then, (It only takes me ten minutes),.
Being IC I don't have much of a choice in this.
And I'm sporty... very active in sports.
But here's the thing: THIN PRODUCT preferrably cloth-covered. and a TIGHT fitting boxer brief or bike-short or whatever like that OVER the IC Product (I mostly wear PADS (Tena Comfort) during the day) followed by your regular sports outfit.
This way the discomfort is absolutely minimal.
Being IC, I started wearing while running about fifteen years ago. I've been running for thirty five years but when I switched to wearing while running I really didn't notice any difference. I guess it depends(!) on the product you're using.
