I've been really into incline walks&jogs lately.
Instead of killing myself on the elliptical
I simply put the treadmill on the highest incline
then walk or jog at a reasonable pace.
I make sure not to hold on
so I work as hard as possible
and basically end up doing a million lunges.
In a 20 minute workout
I burn about 250-300cals
while the boyfriend runs 5 miles
and only burns about 2x as much.
It may sound lazy of me,
but I like that my effort gives me so much
without nearly as much sweat&energy.
(especially when I'm not taking in many calories.)
I can't wait for summer runs on the beach.
Those are totally worth the work.
