So you're a cardio junkie who can fit into skinny jeans, but do you have the muscle strength to tackle everyday physical jobs inside (and outside) your home? Find out with these quick strength tests, designed by Reebok Global Trainer, Sara Haley.

Physical Challenge #1: Rearrange Your (Heavy!) Living Room Furniture

Strength test: Do as many regular push-ups-knees off the ground-as you can without resting. Can't muster "boy" push-ups yet? Do them on your knees (or try the superman push up), and double the number in the key below to see how you rank.

How'd you do?

•12 OR MORE: You've got the girl guns to confidently move that couch.

•7 TO 11: Hit the gym a bit more before you rearrange the room.

•6 OR LESS: Time to call a burly friend to come help you.


Physical Challenge #2: Squatting in a Public Restroom

Strength test: Stand with your feet about shoulder-width apart, hands on hips, and squat down until your thighs are parallel to the floor; hold this position as long as you can.

How'd you do?

•30 SECONDS OR LONGER You're good to go just about anywhere.

•20 TO 29 SECONDS Take it easy on the H20 until you practice those squats (try 15 to 20 every other day).

•19 SECONDS OR LESS You might want to hold it until you get home!


Physical Challenge #3: Pick Up and Play with Your Kids

Strength test: Lie face up with hands behind your head and knees bent over your hips. Lift your shoulders off floor until you feel your abs engage; hold for 1 count. Do as many reps as you can without resting.

How'd you do?

•20 CRUNCHES OR MORE You'll be the one tiring out the tykes.

•15 TO 19 CRUNCHES You're strong enough for a few "airplane rides."

•14 OR LESS Take a core class ASAP!
