hello everyone, first time posting at this site. heres a little info about myself. i have played all types of sports during my teens, i used to weigh in at around 180lbs back then. im now at my 20's , married, own a house and have a great career. Since i stopped playing sports and my job involves me sitting at an office all day i have gained some serious weight. Lunch time is the usual, mcdonalds MCXTRA combo, with an additional cheeseburger .i now weigh approx 305lbs. I decided to start losing some pounds when i woke up one morning and my heart was pounding 100 00 00 00 beats a sec and i figured this was not healthy. My friend told me about this site and since then, ive been hooked. heres some additional info: i have been eating right for the past 2 weeks, i feel like a million bucks, i did not weigh myself yet. Problem: i lift weights for approx 25-40 minutes/day... but 1 thing though... i dont sweat!!! is that normal?! i mean, im tired after the workout, my muscles are hurting etc.. but, not 1 drop of sweat... whats going on?
