ADJUSTING THE BENCH FOR SQUAT EXERCISES
To perform squat or toe raise exercises, fold the Backrest
(15) into the upright position by lifting and pulling it for-
ward as far as it will go.
Remove the Adjustment Tube (29) from the Uprights (25,
26).
Raise the Weight Rests (27, 28) to the highest position
(see ADJUSTING THE WEIGHT RESTS earlier in this
section).
WARNING: Always fold the backrest out of the way
when performing squat exercises. Do not sit on the
seat when the backrest is folded.
WARNING: Always place 50 pounds on the leg
lever when performing squat exercises to balance
the bench.
WARNING: Do not stand with your back to the
weight bench when performing squat exercises.
You should be able to see the weight rests while
exercising so that you can safely return the barbell
when you finish the exercise.
USING THE WEIGHT STAND
The weight stand gives you a convenient way to store
weights (not included) when they are not in use. Simply
slide the weights onto the round tubes on the weight
stand.
