I'm fairly new to working out and I'm not sure what approach I should be taking. Should I be doing workouts that target my whole body, or should I focus on specific areas such as my abs or arms? I am hoping to build some muscle and tone up, but I'm not sure which approach will give me the best results.
Some personal context: I am a 30-year-old female and I work a sedentary job, so I don't get much physical activity during the day. I have never been particularly active, but I recently started going to the gym in an effort to improve my overall health and fitness. I'm not overweight, but I do have some areas that I would like to tone up, like my stomach and arms.
Any guidance or advice would be greatly appreciated!
