Hiya!
I've noticed walking patterns among women are sooooo varied. Some 'walk like guys'. Teens and young adults lead with the hip, the leg doesn't straighten in the air, the knee stay bent partially so long as the foot is in the air, more like a march than a walk?
My advice for how I learned, just glance at women walking around and you can catch patterns. When I first researched, I found a lot said to use heels. Here's my method, push your... 3rd leg... between your thighs in a manual tuck, no adhesives. Then try to walk like the girls you noticed, while keeping *it* in place, preferably towards a mirror so you can see your hip movements. Doing this controls your stride length and makes you keep your legs together more. Use the mirror to make adjustments. Dont look down, just walk in a straight line. If you learn to strut by this method accidentally, it's okay, learn the feeling so you can adjust by feel when you're out and about and notice you're walking differently than other women.
Really hope that helps, it worked for me but your circumstances and desires may be different. Don't worry about walking too much. Unless you're 'swaggering', most don't notice if you're a little off in how you walk.
I still haven't found voice methods, and I've self trained to expand my range as a singer. Let me know if you find anything on that!
