Dating: Does going to the gym really work?
Considering that this question is in the dating section, I'm going to answer it with respect to that. Overall, being more attractive is always going to help with dating. We use physical appearance and first impressions to decide whether or not we want to date someone, and going to the gym can definitely help in those areas.
At the gym, you can do a variety of exercises from benchpress to core exercises (planks, pushups) on the floor. If your goal is to have a more toned/muscular body, then yes, going to the gym can work. It can work if you have a well thought out fitness plan as well as the commitment to go 5–6 days/week. It's also important that you keep a log of your exercises - jot down how you felt each day, how many reps you did of each exercise. Know your progress and your body.
What I found works for me is I go everyday at 6AM. Not only does it energize me for the rest of the day, but I feel accomplished knowing that my workout is complete. Each day I go to the gym, I focus on a different body section (core, legs, arms, back, etc.). There are a lot of different philosophies when it comes to what works and what doesn't, so you'll have to try things out and see what works for you!
