I find mountain biking also is also a bit better for core and upper body fitness than road cycling as there is a lot more variation in movements eg obstacles, drops, grade changes etc. Apparently the extra bumpiness also help avoid the bone thinning effects of road cycling - but that is probably completely negated by full suspension bikes these days. Alas due to circumstances, I've swapped MTBing for cycle commuting. I can no longer say I enjoy riding bikes - but it still beats public transport or being stuck in traffic.
