Although dedication and patience are the most valuable currencies when working on transforming your body, this post is not about that cost. It’s about the actual money we spend, in a form or another.
A membership to a decent gym is about $50/month. You want a personal (shared) trainer, add another $70. That gets you to $120/month or $1440/year.
Apart from gloves, clothing, and good footwear, you also need to consider the time invested. An average workout, unless you’re going to group training, is about 1.5-2 hours. Add at least half hour to get to and back from the gym, and then another half hour to get your shower. That totals to about 3 hours.
You go to the gym four days a week, that’s 12 hrs/week or 48 hrs/month.
