Are you afraid to get big and bulky lifting weights? That is a common assumption/mistake many women have about lifting weights. There was a point where I felt similarly, but I do believe this is the foundation to my workouts and to achieving a healthy body. I am neither big, nor bulky and I would like to think I look more feminine than masculine. Lifting weights for me is the one thing I know helps me shed the "excess" if you know what I mean. Wink wink.
I train about 4-6 times a week; I do a combination of strength and circuit style training with weights and my own body weight. On the circuit days I do about 6 exercises back to back for 10-25reps, with no rest. Most of these exercises incorporate the whole body while alternately focusing on the upper and lower body. At the end of each round there is a 1.5-3 minute rest before I give it my all for a second and third time. These days get the heart rate up and I consider this my cardio.
On strength days I lift heavy weights, and kettle bells in super sets targeting a specific muscle group. I keep the reps lower on these days and give more rest to make sure that I can maintain the intensity for the duration of the workout.
The combination of these workouts is what works for me. Everybody and Every Body is different and you do need to find what works for you and the body you want to build. I am working toward a low body fat percentage based on what is healthy for a woman to maintain,with lean long muscles. If you want to look like a runner there is a different style and technique to lifting, but I hate to break it to you... They lift too! And if you are looking at fashion magazines and want the 'model' body; I hope you were born genetically tall;) and guess what they lift weigh too!
