15 Ways to Tone Your Arms Without Leaving Your Home

Spending a relaxing night at home? That doesn't mean you can't break out the mat and work on improving your planks.

• Start on the floor, resting on your forearms and knees.
• Step your feet out one at a time, coming into a plank position.
• Contract your abs to prevent your booty from sticking up or sinking. Your spine should be parallel to the floor, with your abs pulling toward the ceiling.
• Hold for as long as you can. Aim for 20 to 30 seconds in the beginning and work your way up to one minute as you get stronger.
• Repeat three times.
