Gym not required!!!

Planks

Harder than they look. This is actually a great workout for anyone with a bad back.

Walking

Treadmill not required

Jumping Jacks

No excuses! If you do nothing else to keep fit, do jumping jacks! Do them everyday! Don't think you can? Start with one on day one. Do 30 on day 30. Guaranteed results!!!!!

Skipping Rope

If you haven't done this in a while, you'll be surprised at how much work it is, and how out of shape you are (or in shape!)

Humping the ball

Not sure the benefit here, but if you do this in front of your SO, it will probably lead to some form of exercise. Give it a go, record your results!

Burpees

Kinda like a plank-to-jump. Advanced move if your still in the Doritos's for dinner phase.

Pole Dancing

Not something you can probably do in your house, but still a great exercise. I've never met a stripper with a gym membership or with good eating habits. How do they stay so fit, you ask? Working the pole!

Sit ups

Sit ups suck. I hate them. And if you know what you're talking about, you do, too. Crunches are just as good for developing your core.

Important detail: neither crunches nor sit-ups will give you abs like this. We all have reasonably well developed abs. But most of us also have a protective layer of fat over them. Core exercises will not help with love handles, muffin tops or beer belly's. Dropping your overall body fat is the only cure.

Hula hoop

Want to exercise with your kids? Hula hoop!!!! Just do it already. It's fun and you'll look great doing it. Nothing is sexier than watching a girl move her hips.

It's a great core exercise, but more importantly it gets the heart rate up, and you can watch TV while doing it (if that's your thing). Makes less noise than a treadmill, and cost way way way less. Bud don't buy a $5 hoop. One that works well with a good counter weight inside is closer to $20. If you have a larger frame, get a larger hoop. You'll struggle to use a child's hoop.

Boxing!

Whether your are shadow boxing, using a bag or beating on your partner, boxing is an incredible exercise. If you are out of shape, there is no way you can hit a heavy bag for 3 minutes straight (if you are applying your self). It is amazingly tiresome.

This

This is proof that hot chicks look hot no matter what they do. It's also proof that you can find a way to improve your health without any special equipment.

Every day is a chance to improve yourself. It's never too late to start, and anything you do, no matter how small, has an impact.

GO BE AWESOME!
