Yes, weighlifting helps a lot! One pound of muscle burns 50 calories a day, and one pound of fat burns 2-5 calories a day. Also, weightlifting increases your metabolism for a while when you lift the weights, as does aerobics and such, but it also keeps it higher for longer than aerobics. But you should do both weightlifting and aerobics to get the full benefit. Because if you don't lose the layer of fat that's on top of your muscles, then you won't see your muscles very well. Good job on losing weight, and keep drinking plenty of water! lol God bless you! P.S. My e-mail is: arwen_elf_16@yahoo.com if you want to e-mail me (this goes for anybody)
