I understand what most women with a bulky, unfit body feel when people look at them and give a disapproving look. I took this way due to such womanly feelings. I feel motivated when a woman lets me know that my coaching did some good to her, and she’s happier than ever before. In addition to the daily workout recommendations, I also provide counseling to those who feel down amid a hostile social atmosphere. I write a lot to inspire fellow women and those who wish for a modern, elegant lifestyle. I hope you would benefit from my write-ups.
