I use my Bob XL as part of my cardio fitness routine. It's very easy to raise your heart rate with fast punches and combos to poor old Bob.Mine is located in the garage and is filled with sand and then when i couldn't fit any more sand in i topped off with water. Took a good 2 hours to fill with sand due to the small fill cap, would have been easier if i had had dry, free flowing sand.It is extremely heavy, i can barely push it along the floor so i wouldn't recommend it if you need to regularly move it out of the way. I weigh 215 lbs, can bench 315lbs and I can't get it to budge with hard punches. It sits on a concrete floor, may be different on a polished wood surface. I recommend this model over the standard Bob, it's heavier and has more target areas to hit.I would advise wearing bag mitts when hitting Bob with any force, especially due to the moulding of the face it is easy to bruise knuckles.If you are into martial arts/boxing then nothing can replace a decent heavy punch bag for developing punch power but for average hitters like myself or for those who need a quality fitness workout then the Bob Xl comes highly recommended!
