Should girls not lift heavy weights?

A mix of weights, cardio, bodyweight exercises, right nutrition, sleep, patience and having fun while doing all of these things together is the easiest and most effective way to loosing weight.
An OLD MYTH says that girls should not lift heavy weights it will make them look like dudes with boobs. ..well I call BULLSHIT !
One of the most effective weight loss approaches is by adding weights to your training routine, and by weights I mean go as heavy as your technique allows you to go!
