Hey dude, Thought I'd add my wee setup to the list of awesomeness on your blog. My hobo's my shed, or at least half of it.
Contains:
Kettlebells - 12kg, 2 x 16kg, 24, 32
Med balls - 6,7 & 9kg
Bars + 193kg of plates
Hex dumbbells - 12.5kg, 15kg, 20kg
Abmat
Power tower
Sledgehammer + tyre for hitting.
Rings (usually hanging off the apple tree)
Jump ropes
Treadmill
Squat rack
Rower (sadly not a CII).
Plus, just outside there's a scaffold A-frame for pullups etc. and a wall ball target made from a scaffoldling plank.
