What Journey after 2 times Hardcore?

As of now, I’ve done six journeys since starting my journey on Freeletics, the last two of which were Freeletics Hardcore.

Since a month or two, I’m going to the gym on a semi-regular basis, and do my workout there, however, I still frequently (or over some period, e.g. holidays) train at home, with little to no equipment available to me (sometimes a pull-up bar, that’s it).

Knowing this, what would be the most suited journey for me next, as I strive to gain weight by gaining muscle mass?
