Due to your upper body being almost completely free and independent of your
lower body, you can perform a number of upper body exercises while you do any
form of lunges including walking lunges. Since you will likely already be
holding a pair of dumbbells, you can hold them in the high hang position and
perform a shoulder press in between each walking lunge.
Doing two compound exercises at once will work wonders for your
metabolism, overall functional strength and coordination. While doing
walking lunges you can either do the shoulder press at the bottom of your
lunge or doing it while you transition to the other leg. This is probably
most natural because you can pause for a second, correct your form and
execute the shoulder press flawlessly.
To increase the difficulty of the walking lunges with shoulder press you
can obviously use heavier weights but also perform the shoulder press while
standing on a single leg. This exercise fits perfectly in any workout in
which you work your legs and shoulders including fat incinerating full body
