I'm doing more cross training to get myself back into shape after a bit of a rebound (back up to 250 from 235 in mid-summer.) I've always been a hiker and even when I can't get out to the mountain trails, I still take my dog out for an evening walk of a few miles on the neighbourhood trails... but those trails are all flat.
I started up a step routine this weekend, and my calves are just screaming. Even after a 4 mile uphill hike I've never noticed this level of soreness. Anyone else ever surprise themselves with what ends up sore after starting a new workout routine?
