so i lost about 25lbs in a period of 6 weeks, mainly by cutting calories and lots of cardio. my daily calorie intake i reduced to between 1200 - 1600 calories and i do a 60min session daily on the eleptical machine. the machine says i burn about 700 - 800 calories doing that....my problem now is that i feel so damn weak....i have a lot more energy but the other day i wanted to workout my legs i had trouble picking up the 45lb weights (plate) to put on the machine....any ideas?
