FB Reach -> Strong -> Mass -> .... What Next?

I'd love some suggestions on how to progress through the Fitness Blender programs!

Over the last few months, I've managed to stick through and actually complete some programs (in the past I've had a lot of start/stops with Fitness Blender).

I started with two rounds of FB Reach, then completed 2 rounds of FB Strong (R1) and am now about to start my 2nd round of FB Mass. I figured doing 2 rounds of each program helps me stay motivated to continue exercising with a before/after progress comparisons (since the scale and inches refuse to budge).

I'm trying to figure out a way to inch my way into programs with more cardio / HIIT mixed in but am not sure where to go after my next round of FB Mass.

I'm currently thinking either Flex/Booty combo or FB30 R4... or maybe something else?

Any suggestions?

Thanks in advance!
