Congrats to Samuel and Gabriel. Both were recently promoted to blue belt.
Everyone has a different BJJ journey. Some people can only make it to training once or twice per week, while others come to training almost every day. Both Samuel and Gabriel are in that second group and they have improved a lot in a short amount of time as a result.
But just showing up is not the most efficient way to get better fast. Both of them also made heavy use of our open mat timeslots where they reviewed our curriculum, studied jiu jitsu and asked the upper belts a lot of questions.
If you want to get good in a short amount of time, spend as much time as possible on the mat and also study as much jiu jitsu on the side. Follow their footsteps and you will have similar results.
Of course this is only one of many possible paths. A path that clearly favours the young who don't have a lot of responsibilites clogging up their schedule already. If that's not you, don't worry just because you can't spend most of your evenings on the mat. It's a marathon, not a sprint. Training twice a week for the rest of your life is much better than training seven days a week for a year and then quitting.
