Of course. More effort/min. = more energy consumed per minute.
However: I don't know about you, but *I* can't lift weights for 30
minutes or more w/o a break.

Define "best." One argument is that aerobic/cardio workout below
your anaerobic threshold is the "best" way. (That's what I
originally learned.) Another is that high-intensity interval
training is the "best" way. Yet another is that building muscle mass
is the "best" way. In truth: Probably the "best" way is what works
for you. For me: That's all three. I do full-body workouts,
followed by at least 30 minutes of cardio, three times a week. One
day a week that cardio is HIIT. Why only one day of HIIT? One
article I read suggested that high-intensity cardio is
counter-productive to muscle gain. So I compromise by doing it only
once-a-week.
A week-ago-Saturday I went wild. After doing pyramids on strength-
training, I did 10 minutes at AT cardio on each of all five machines

. (Treadmill, stepper, rowing, upright stationary bike,
elliptical.) It's good to mix things up on occasion.

IIRC, somebody not long ago pointed me to an article that said
"low-intensity" cardio results in elevated energy consumption for
about 1/2-hour following the work-out, whereas HIIT results in
elevated energy consumption for up to six hours. Muscles continue
consuming (more) energy (than fat) indefinitely.

I do 30 minutes of cardio as 10 minutes on each of three out of five
machines. Some argue it's better to do a continuous work-out on a
single machine than to interrupt it by switching machines. I like to
vary the workout and switching machines helps avoid boredom. I
figure it's better to have a sub-optimal work-out than stop entirely

. I do move from machine-to-machine as quickly as possible. As
often as not, my heart rate is actually higher, when I get to the
next machine, than it was when I left the previous machine.

You're welcome. Be advised that I'm no expert, by far, in these
things. Surely somebody far more qualified than I (not difficult)
will come along with better and more accurate information. They
usually do
