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.
Weight exercises like deads, squats, and leg press stress the heck out of your lower body - hamstrings, glutes, quads, calves and all of the little accessory muscles. It's necessary strength-building until you reach your realistic goals for your maximal life functionality.
For the calisthenic component of your fitness program, though, you can throw in a few sets of lunges to make your legs burn for 24 hrs. (That is not lactate burn, it is good muscle-damage, micro-tear burn/ache). I do 3 sets of walking lunges, with or without hand weights, weekly. Even though it counts as calisthenics, I think it toughens up the legs even though it is more endurance than strength. Good pain!
Readers are tired of my preaching that calisthenics are a necessary fitness component but I will persist. Contra Rippetoe, we preach a balance of approximately 1/3 weights, 1/3 cardio intervals, and 1/3 calis (including what I term "heavy" calis like Farmer's Walk, pull-ups, push-ups, heavy ball slams, lunges with weights, weighted planks, etc) - while agreeing that real weight training is the most important and effective fitness component.
Last week cut up tree that was down in neighborhood. Took wood home. First trip was (deep) wheelbarrow full of greenest logs. 3 (short) blocks all modestly uphill.
I still believe that calisthenics are an integral part of any fitness regime. I was thinking about when I was doing karate and kick boxing, I didn't lift weights at all for 3 years, calisthenics only. A lot of body weight squats and various types of push ups, yet when I did try a bench press after 3 years of no weights I was still able to do a 200lb bench press. I weighted 170 at the time.
