Upper body: Lateral bear crawl

* More challenging

Begin in "up" part of push-up with core tight and body in straight line, hands outside shoulders, feet together. Do one push-up, then move right hand next to left hand and right foot out to the right so feet are wider than shoulders; do another push-up. Return to start.

Repeat entire move 10 times; do 10 reps in other direction.

Next: Core: Rotational mountain climber
