Plank-mountain climbers

This workout is perfect for targeting arms and abs. First, plank for thirty seconds, then quickly switch to 30 seconds of mountain climbers with no break in between. Challenge yourself to not put your knees down on the floor to strengthen abs/arms.

Bicep curl

Whenever you grab a heavy item in your house or around your office, do bicep curls to strengthen your arms and tone muscles. Complete one minute on each arm. Ideally, you want an item that challenges you but doesn’t ruin your form, so don’t pick something too heavy.
