There will be different weight lifting games in the gym , each will award 3 skills, also the strength is not a limitation at the moment and it is not needed to have more than 3. Expect heavy weights lifting where you will click certain key's (on adroid certain spots) for example, maybe we can decrease the number of clicks needed, making this mini game easier. Visit our discord and open question there, if more people will vote for it, we will do it.
