Yes, you need to start with a rigid MTB to learn proper form for a decade first, before you can graduate to a hardtail. Another 10 years later, you're skilled enough to be able to take advantage of a full suspension bike, but by then you're also a father of 2 and husband to a wife nagging you to save your money for a new Ford F350 instead so she can drive the lil rats to school safely and meet her "fitness coach" in the afternoon.
