Honestly, I've always enjoyed being active. As a child all through primary school, I was definitely doing more than the Healthy Living Guidelines for Children have as their minimum (they say kids need at least 60min of vigorous activity daily, and I was easily playing hard 4 hours most days of the week).
I was very resilient to going tot he gym the first time. My dad made me go. I thought gyms were just places where people hang out on treadmills to lose weight. At the time I was underweight. When I saw that they had weights, I fell in love. At the time, I had also had a brief history of martial arts training at school and had been doing push ups daily, and bodyweight squats frequently (probably with attrocious form for both). I wasn't able to stay at that gym for long - my parents had only signed me up for a 1month membership, and I had no income of my own or even pocket money from my parents, so I couldn't afford to stay at the gym. Later in the year I did swordfighting for 6 months, and then the following year I got my first 6-month gym membership. By that stage, I knew exactly what I wanted, and it was to be STRONG. Not big, just strong. Well, my training was pretty sloppy for achieving that goal, and my nutrition was even worse, so I spent a LOT of my training life spinning my wheels. I've gotten a bit smarter in recent times, and have made some progress. The goal is still the same.
