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.
It looks to me as if lots of people do weights and cardio on the same days. I never do that, unless you count a little jump rope between lifts to loosen up.
My reasoning is that a weights day calls for at least one (or two days for those over 40) of active muscle recovery, by which I mean just calisthenics or "cardio." That's why I have weights days, "cardio" days, and calisthenics days.
However, if you do cardio and some heavy weights on the same day, do the weights first. If you do them the other way around, you may not have the oomph to move the amount of weight you need to.
Most of my cardio comes from my 5 times a week bike rides. I do use the rower for about 10 minutes before lifting weights, mainly to loosen up and get the blood flowing. If you are lifting heavy you don't really need cardio on those days anyway. 3 sets of 5 of heavy squats will give you a pretty good cardio workout.
We are having a difficult time getting our energy up in the morning. Coffee (1tsp sugar) and a little treat, or muesli--that's all it takes and we are crashing and it is only 0830? Any suggestions as to how to get more energy in the morning?
