We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Generally speaking, your body derives little benefit from an exercise itself because exercise (as contrasted with a normal active life) is designed to stress the body, to hurt it, really. That's why going for a hike, playing a round of golf, or playing doubles tennis is not exercise: it's recreation.
The benefits obtained from exertions are obtained during the recovery phase from the stress and damage. This can take a few days, and much longer to repair damaged muscle and to build new muscle fibers and blood vessels and to ramp up neural connections. Progress is thus slow.
The approach I use for recovery is to try for a good diet with high protein and enough carbs so as not to lose weight or maybe to gain some in 5 smallish meals/day, and "active recovery" meaning days of aerobic exercise between days of intense work-outs. Also, days off for pure recreational activities like sports or hiking.
Saunas are great for the off days or right after a brutal workout. They ease aching muscles, but more importantly promote blood flow, growth of tiny new blood vessels, and even more sweating than from the most exhausting workout. This helps the body repair any damage done. Not to mention, it actually burns calories cooling the body down...and feels great. Keeps you from getting colds, etc from all those gross germy gyms too (I prefer the outdoors and cold ocean swimming myself)...just make sure you check w yr MD if you are an older guy with high BP and/or heart issues before beginning, in which case you might start gradually rather than immediately spending 40 mins at 160-180 degrees...
Disclaimer: I do not own a sauna installation business.
"The benefits obtained from exertions are obtained during the recovery phase from the stress and damage."
Stress and damage. Think about those words. Think about those words when you are 70 or 80 years old, are in constant pain, limited to a wheelchair and looking forward to your 4th knee or hip replacement (or both), not to mention nerve blockers for your sciatica.
Exercise should IMPROVE your lifestyle and older age, not destroy it.
- Eric Liddell: "I believe God made me for a purpose, but he also made me fast. And when I run I feel His pleasure."
Running is spiritual, brings one closer to God, and worth the price we later pay in aching joints. God created us to live intensely when young, but not to vainly chase after eternal youth. Cf: Ecclesiastes. IMHO weight lifting is some kind of penance for every sin one ever committed. A misery. But whatever floats your boat...
