While there seems to be no end in sight for the economic strain and with gas prices on the rise again, belts across the nation are tightening and Sunday morning paper coupon clipping is becoming a family activty. We're trying to save dollars and cents any way we can. And while we're all figuring out what's important budget-wise, gyms have perhaps become one of the "frivilous expenditures" versus "necessities."

Spending close-to or over $100/month to work out is not topping many lists anymore. If you've found this the case in your day-to-day, fear not. Here are 10 at-home exercises to keep every part of you slim, while hopefully adding some weight back to your wallet.

Pushups:

This simple and very effective activity works your chest, abs, lower back, shoulders, triceps and glutes while burning calories and building muscle.

Bodyweight Squats:

With your hands behind your head, chest out, and elbows back, sit back at your hips and lower yourself, then squeeze the glutes and raise yourself back up.

Pullups:

Pullups work the latissimus dorsi, the larget group of muscles in the body. Important note: when lowering down from a pullup, go slow and resist rather than merely dropping back into the starting position.

Step-ups:

Stairmasters, step classes? No. Find something in your home, step up onto it, and step off of it. Go as fast as you can for as long as you can. You'll blow those machines and expensive classes out of the water.

Plank:

Get yourself into the pushup position and keep your abs tight. Hold this position as long as you can. After even 30 seconds, the strongest body builder will be sweating like they're under interrogation room lights.

One-leg Romanian Deadlift:

This simple exercise will not only work muscle groups, it can help with overall balance. So if you're strapped to an office chair all day, this is your chance to give your hamstrings the much needed attention they don't get in the cubicle.

Stick-up:

Think simply raising your arms won't do much for your health? Think again. Stick-ups, when done correctly, are a tough back exercise that challenges your central nervous system and burns calories. Stand again a wall, raise your arms up, keeping shoulders, elbows and wrists in contact with the wall, and lower your arms to the starting position.

T Pushup:

Sculpt your abs with this pushup variation. Do a standard pushup. While your arms are straight, lift your arm up so your body forms a "T". Bring it back down, bend your arms and do another pushup, this time raising your other arm. Alternate.

V Up and Roll:

This variation of the classic crunch works your body harder and smarter. Lie flat on your back, contract your abs and roll yourself up by lifting your legs and stratching your arms towards your toes. Pause, then return to the starting position.

Shoulder Press Pushup:

Weights take up space. And with the size of houses getting smaller, you need all the space you can get. The Shoulder Press Pushup not only utilizes your body's weight, it burns calories and provides the same benefit as lifting heavy things over your head...all the while upside down.
