Women sometimes have the impression that if we lift weights, we'd just become Tyrese. Men produce hormones that allow them grow larger muscles than women, and so doing cardio and lifting weights alone will not usually make a woman huge. A lot of the women you see that have larger muscles are either not doing cardio to burn the fat over the muscles, or are taking supplements because they want to look that way. Building muscles actually helps your body stay in fat burn mode, and gives you that toned look. Don't neglect your lifting!
Cheers Eights & Weights!
