Hi Kendall! Welcome to the forums! So nice to have you join us! I'm thrilled to hear of your success. Keep up the great work. Just remember slow and steady progress. Nothing drastic or it will not last. So far, you sound as if you are doing it all at a very nice steady pace....Go Kendall.
It is always a good idea, and actually recommended, that when losing more than 20 pounds to check with your doctor first and let them know of your weight loss efforts. Since they have your personal health history records, they will be best suited to give you specific suggestions as well as highlight some issues for you that will be helpful to ensure your success too.
We, of course, will love to encourage you too :7
As far as your neck discomfort is concerned, that is very normal and quite common. Your neck muscles will get sore from keeping your head elevated for long periods of time. Be sure to keep your hands behind your head to assist your neck (but be sure that you are not yanking on your head too). Also, go only as long as you can before the discomfort really takes over. Each workout try to add on 10 to 15 more seconds of ab work. Eventually, with each and very workout, your neck muscles will get stronger and you will not get nearly as sore as you once did. Also, as you lose weight, your mobility will increase too and you will be more comfortable doing many of your exercises too.
As far as how many calories you burn per workout, that varies sooo greatly from individual to individual that there is no way for me to answer that accurately. Usually when you start an exercise program you burn more calories doing a workout than you do once you become conditioned to it. That's why we like to vary our workouts as we become more experienced. But on average it is safe to say that you burn anywhere from 6 to 20 calories per minute depending on your energy output. For example, while you are in your warm up phase, you are burning less calories than when you are in the heart of your workout. But don't skip that warm up or push it too hard in the warm up....thats the most important factor in giving you the safest most intense workout to follow.
Ok, I have babbled long enough. Welcome aboard Kendall! Good luck and keep us posted
