fookin hell, i used to be able for 6 reps out of 220kgs, i didnt heavy squat for a good 6mths due to knee probs. gradually have been building them back up, i went up to 160kg today and thought my lungs were going to explode after 6 reps, so frustrating, i dont seem to have the piff for 'em anymore. looks like squats are out for me.......
