So I find myself wanting to take better care of my health and in particular fitness based on recent ecapades ... like oh shoot I need to get in better shape if I am going keep up with these activities.....  
Anyone else get this feeling after spending time with these amazing ladies?

There was a point in my life that I like most busy professionals I allowed myself to get a little out of shape.
I hadn't deteriorated all that much in physical appearance but definitely loss muscle tone and most of all physical stamina.

I have never "let myself go" to the extent that it affected my fucking ability, but I have been with some particularly hot women where it became more than just BCD "sessions" and we would often go out in public and while I can't help getting older, I refuse to be "that old fat guy" with the hot girl.  

I usually train at the gym 4 times a week but, travel and some medical challenges have made my work outs sporadic at best this year.
At my age the fitness goes away really fast, but I'm lucky that my muscles have a lot of memory and strength comes back pretty quick. When the strength comes back my aerobic and anaerobic ability gets a big boost. And my ego gets enough of a boost to stop feeling less than and just have fun.

give me advice on nutrition and exercises to do.

It doesn't take a lot to stay in shape, once you get there.  It's a slog to get into the groove, but it does pay off.  It took a while to find what worked for me at my age (67) without biting off more than I could chew.  After some setbacks and lots of uncomfortable pain I've settled into a rotation of 3 days aerobic (30 min bicycle outdoors or indoor spin depending on the temp) and 3 days strength training (10 to 15 min resistance bands) weekly, with one day off as my reward.  I've cut almost to zero the amount of red meat and sweets I consume, and eat lots of beans.  The benefits have been a 20 lb weight reduction, muscle definition that I can see, and waaay more energy.  My resting heart rate, cholesterol, and blood sugar are all lower than they've been in decades.

is why the reviews show so many guys, especially older guys, finishing in standing doggy with the girl bent over the bed.  Its the least physically taxing position for the man.  If you are going to be active instead of passive in CG, it requires abdominal strength, not necessarily a six-pack, but some good ab muscles that are worked out regularly.  Mish requires significant upper body strength if you are going to last to the end without putting your weight on the provider.  If you are in mish with a provider and she puts her forearms over her breasts, then you know she has had a look at you and thinks you can't make it to the finish line without collapsing on her.  This defensive technique has been told to me by several girls during discussions about this very topic of fitness levels of their customers.

AMEN BROTHER. I'm 58, a bit heavy, and suffer from many of the common maladies many hobbyist's suffer from. Even with using a little pharmaceutical helper, some times my stamina just isn't what I'd like it to be, and sometimes little "willy" just doesn't want to cooperate..SHIT.  
Not sure what the solution would be, i'm trying to exercise more, working to get into better shape, and am sure it will only enhance a future meeting. All the best!

but if it's affecting your sex life, you really do need to make some changes.

watch the quantity and what food we eat/drink as well as keep up an active lifestyle.

I have been told many times I have the body of a Greek God.

How many times have we heard that refrain? It's so true when it comes to health, fitness and exercise.

It really gives the lady a sense of security in missionary. Push ups are good in a pinch.

they should be doing their sets with their body weight.  This will get them through 20-30 minutes in mish with both arms extended with elbows locked and no weight on the girl.  To get more out of pushups, do them from a decline, with your feet up on a chair.  This focus' more of your weight into your upper body for better resistance on the pushup.  You can do half as many declined pushups and get the same benefit because they're more efficient.  Its a time saver.  

and even as recently as two years ago, I used to get muscle aches in my lower back and bilat thigh after each sexcapade and it was painful to walk for at least a couple of days afterwards, but that's nothing a little Bengay won't cure. Now I just find a position I'm comfortable with and stick with it, but that's no excuse to not get fit, even if long term health and wellness is my only incentive for doing so. I also had trouble getting and maintaining an erection, (I am not an old man) and for 7 years I had to rely on herbal viagra just to get it up. That was until I quit drinking soda entirely and started consuming more fiber dense foods. Now I can get a fuller, firmer erection even after a few alcoholic drinks, and I also have more energy to go with it.

Everyone should want to look good naked.  lol Smile 4 me!

A wonderful idea that makes complete sense....which is why our government will never go for it LOL!!

To quote Dean Wormer (from the immortal movie "Animal House') ..."Fat, drunk and stupid is no way to go through life son."

I was 155lb for 30 years and gained weight when I stopped running.  Digusting things happened when I got up to 200lbs.  I could not cut my own toenails, I could not wipe my own ass, and I could not see the action when I was getting a blowjob.

Same place, man.

Why start now?

Yeah, I'm on hiatus from the hobby now to get in better shape. Doing it mostly for myself, but I figure the sessions will be more enjoyable for the both of us, if we are genuinely mutually attracted to one another.

"that old fat guy" with the hot girl, but fortunately for us, there are others that don't mind, so we settle for just being the "old" guys with the hot girl.   Its just about staying fit so you can do long division.  The more times 58 goes into 30 or even 25, the happier they both will be.  

Best comment!

I had a partial rotator cuff tear in my left shoulder. Overhead presses, starting light and working up, fixed this issue, and it hasn't come back, although I'm still working on shoulder mobility.

Alcohol as a human tissue preservative, so I think your lifestyle could still be called healthy if it works for you.
