weight loss boost? how much exercise?

Simplistically you need to burn 3500 more calories than you consume to lose a pound.
Lean muscle mass burns calories at a faster rate than fat body mass so weight training is generally recommended in at least part of the exercise regime

Good luck!  I need to take my own advice and start doing this stuff again, too.  

I routinely add workouts from Oxygen into my routine. I do have a set of 10 and 15 pound dumbbells that I use, but you can do a lot of these exercises with soup cans, water bottles, etc.

Dips.....use a step in your home. Straighten your legs and push up/down with your arms at your sides. When this gets easy put one foot on top of another.

This is hard to do with a chair as the seat of the chair is too tall and a chair isn't steady enough.

Drinking at least 64oz of water always jump starts my weight loss. I also agree with weight training.

Can you get a tension band? They are really easy to pack, store and travel with.

I echo the others, add weights, or a resistance band workout. I walk enough a day (on average 12,000 steps, which is 5 miles for me) that I don't add on additional cardio. Instead I do the Upper Fix, Lower Fix and Dirty 30 workouts from the 21 Day Fix series 5 days per week (typically Monday through Friday). I always do Upper Fix twice a week and then alternate between doing the Dirty 30 and Lower Fix twice every other week. And I log all my food and water...that part is key for me!

Good Luck!!

We do a quick 5 minute workout at work everyday. Start with 1 minute wall sit, 1 minute plank, 30 crunches, 10 push-ups and 15 squats. We up it as it gets easier, we don't get sweaty and we don't need equipment (well we have yoga mats because our flooring is gross!). Maybe your children would enjoy doing it with you (mine don't .

Eat less carbs and sugar. Avoid stuff like bread, pasta, rice and sweets. You don't have to be extreme with it but if you cut back for a while you should see your weight move down.

Greatist.com has a lot of body weight exercises, you can search there. And fitnessblender.com probably has body weight exercises too. They are a *great* website for exercise/weight training videos, all free.

I just downloaded a Nike training app onto my phone. It was free and I just did a 30 minute workout that kicked my a$$. It requires Dumbbells, but again you could use soup cans or water bottle
