My first suggestion is to quit weighing yourself every day. Due to water or a bunch of other factors your weight is BOUND to fluctuate, even within the same day. Pick a day and time each week to weigh yourself and stick to that. If you're going to WW and being weighed there, then that is your time to weigh in - don't become obssessed by the scale. I'd also suggest that once every few weeks or so, get out the tape measure and check your hip/waist/upper thigh/chest measurements, and keep a log.
Second suggestion is to TRACK YOUR FOOD. As has been said here so often, during weight/fat loss, nutrition is the most important aspect for weight loss (or the lack thereof). Check out
www.fitday.com which is free to use! I see SO many people at my gym EVERY DAY, who are there EVERY SINGLE DAY, doing the same machine every day...and they have not lost any discernable weight. The reason? Well, it's not like I've interviewed them or anything, but judging from my OWN personal experience, I think it's fairly safe to say that they haven't been watching their food intake very closely. I myself was in the mindset (back in the mid 90's) that as long as I did a buttload of cardio, I could eat whatever I wanted 'within reason'. Well...maybe that worked for my DAD when he was a KID and spent all day every summer in the FIELDS or working around the farm doing manual labor...with three huge meals a day...but 'tain't that way for most of us - who spend an hour or so at the gym and 23 hours basically either sleeping, sitting on our butts in front of a computer, doing light household chores (and trust me...compared to say, 40/50/70 years ago, they're LIGHT!) plus the fact that we have all that wonderful fast food and junky snacks that didn't exist back then...well...there ya go.
If you're doing WW (we had a thread on that earlier this week) I'd advise that you steer clear of the pizza and cake and marshmallows that they show in the ads as 'allowed' in the points system. I'd also advise keeping the processed/prepared WW foods at a minimum (it's been awhile since I've been to a WW meeting, but I imagine that they still plug the frozen desserts and products) and sticking to clean eats - lean protein, fresh veggies, healthy carbs and fats - as much as possible. And track that intake - even healthy food can make you fat, if you eat enough of it.
As far as exercise - I'd say to change up your workouts. Instead of WATP, once a week or so, throw in something a bit more challenging. Same with the weight training - if you're doing the same exercises every week, your muscles will become accustomed to it and you'll stop making progress. Variety m'dear - variety. Plus it'll keep you from getting bored!
