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.
Like our editor, I am more interested in vigorous fitness for functional life and endurance rather than in conspicuous muscle mass. However, it has not escaped my notice than some mass has a signaling effect on females.
Limitations I have found in my (recent) mixed cardio-resistance-endurance program are strength and power in my extremities, ie forearms and lower legs. Those tend to be neglected in resistance work. They are more or less expected to respond in strength to the other things you do.
That is true to a point, perhaps, but, for examples, but my dead lifts and kettlebell walks are limited by my grip strength. Lower leg strength is needed for everything you do, posture and agility, and especially to prevent injury.
What I am learning is that I have to strengthen everything to pursue my maximum functional endurance. The two go hand-in-hand.
For grip strength I hold a barbell with my arms fully extended - try not to cheat by pressing the barbell into your legs. I do it in the squat rack with the support bars set about 1 inch below my hands. I do 3 reps attempting to hold for 30 seconds per rep, but usually reach failure before I get there (ie dropping the bar onto the rack). Once I can do all 3 sets for 30 seconds I'll increase the weight for the next workout and start over with 20 seconds per rep, eventually creeping up to 30. Rinse and repeat.
Another version which I use at hotels: hold onto a pullup bar (feet off the floor of course) for as long as I can. Again 3 reps, aiming for 30 seconds each. Thus far I fail every time!
