I am five foot, ten inches tall, and I weigh approximately two hundred forty-five pounds, which places me just under the obese marker for my age. I enjoy walking every day, and whenever possible, I indulge in cycling. While I don’t currently play any sports, as none really pique my interest, I do recognize the importance of physical activity in maintaining my overall well-being. I plan, in the near future, to join a gym where I can utilize various equipment like treadmills and bikes, as well as participate in cardio-focused activities. Over the past two weeks, I walked to my local library and visited several businesses in my job search. During this time, I've averaged about eight miles per week. My exercise plan is designed to help me slim down gradually, as I am walking consistently, and securing a job will not only provide me with the funds I need to join a gym of my choosing but also offer m more structure to my daily routine. By engaging in regular exercise and creating better habits, I hope to improve my health and fitness, leading to a more fulfilling lifestyle.
