Advise of exercise for someone 100lbs overweight

Yes, lift weights. I personally recommend Chalean Extreme for a starter program or get the book New Rules of Lifting for Women. Bodybuilding.com has some great info too, I've heard good things about Jamie Eason's program.

I second the suggestion for Chalean Extreme! I love her. I am about to start the program again since I took some time off lifting to train for a half marathon. She is great and super motivating. Good luck!

I have a friend who just finished her first marathon and she said that she really regretted not doing more strength training as part of her training because she felt like she really wasn't strong enough in the end. She finished it, but is now doing lifting. Just FYI. YMMV, etc.

I'd start of easy with light walking and, if possible, work in low-impact cardio, such as elliptical. As your body gets used to things, ratchet up the intensity. Weights are important, but I'd not start with those; I'd work into them as time went on.

I started out doing aqua aerobics b/c my knees were so bad and it was difficult to do much more than that. Aqua aerobics provided both good cardio and toning for me. After about 4 months of aqua and losing a good amount of weight I wanted to up the intensity and was able to add Zumba. After a few months of that I started doubling up my classes and doing aqua and then zumba. I didn't add weights into my routine until about 6 months into my journey and that is when I was also able to up the intensity more and started doing spinning. I now spin 6 days a week and do weights for 4 days of them. I do spend a lot of time at the gym (no kids) each day because I am seeing such amazing results. My advice is start slowly and as you lose weight you will be capable of doing more and switch things up.

Take your 2 year old in a stroller on walks with you, adds weight and resistance along with some cardio; try to find some hills and control your speed. That way you get a good workout in and good bonding time with your baby.

Lots of great info from folks here. I would say this (I have not done this myself, officially): make a workout bucket list. In a recent post, I talked about how I wanted to jog a 1/2 a mile, then my BIG goal was to do a mile. I had sort of forgot about that, and then last weekend I jogged for 2 miles straight. I found the list last night and was so happy! That being said, think of all the things you don't do now for whatever reason it may be jogging, kayaking, rock climbing, 5k runs, etc.

Take that list and put it up somewhere visible. Then when you get bored with what you are doing, take a look at the list and choose another exercise from your bucket list. Here is the really cool thing. Most likely, if you are like most of us, you will look at the list when you are at a plateau. By doing a new exercise you will probably shock your body past the plateau! Double benefit!

I have also ordered the 30DS dvd which should arrive in a few days.. i was feeling pretty confident about it, but now while im waiting for it to arrive i seem to be almost talking myself out being able to do it..

I've done 30DS and it's a fantastic, challenging, time-efficient full body workout. You'll love it. I did level one for longer than it said to get back in shape a bit before progressing.

30 DS is high impact (the cardio portions) ...... you're young (by your picture) so you might be fine. If you get sore knees...trade off days by doing something lower impact, at least until you can build up.

For something that is strictly strength training (and low impact)

I'm 5'1" and I was 228 at my heaviest and I did mostly cardio on the machines and lots of walking for the first 2 months. I was losing weight but it wasn't until I started strength training that the weight really flew off. Since I didn't know much about lifting weights and I was nervous about doing it on my own after such a long break from exercising, I got a personal trainer. I highly recommend you work with a trainer if you can afford it. He's really helped me, not just with motivation, but also learning proper technique and form. He also pushes me to do more when he knows I'm ready even though I don't think I'm ready. One day he made me do unassisted pull ups, which is not something I would ever do on my own because they're really hard.

Good luck!

Hi
I tried not eating (nothing but water or black herbal tea)after 6pm and lost 17lbs.(one lb a week), also if I could sit or stand rather than lay down I would, little tricks are better some times when you have a bit of weight to loose. Everyone has a little trick that works for them.
Good luck

I like nerdfitness.com
Also I have been reading "Body by You" which is the female version of "You are Your Own Gym." There is a $1.99 app available and I like that I can customize it to MY strengths and weaknesses and it gives a list of easy to progressively harder strength building excercises. There are free videos that show examples and if you have a barcode scanner, you can scan the code in the book and it shows the video of how to do the exercise instead of just guessing from the pictures in the book. (Though the pictures are great, too!) I got it from the library, but am seriously considering buying it because I use it as a reference so much! Works GREAT with the app!!!
