Low Bounce

Less bounce means more predictable bar travel when dropped, which allows you to workout safely in small spaces and at home. The dead bounce means greater protection for the barbell as there is less impact on the bar.

What Plates Should I Buy?

To answer your question it all depends on your current bodyweight/muscle mass: So if we were to take someone weighing in at 80kg we would take that number and multiply it by the given numbers down below, giving you your 1 rep max for your bench, squat and shoulder press. Through this you can decide/narrow down which plate set/bundle would be best suited for you.

Person weighing 80kg

Bench 1 Rep Max = 45kg (.56 x bodyweight)
Squat 1 Rep Max = 65kg (.81 x bodyweight)
Shoulder Press 1 Rep Max = 35kg (.44 x bodyweight)

Can I Buy the Plates in a Set?

Yes the plates are available bundles/sets. Here are the available sets for purchase:

'50KG Bumper Plate Set' = 4 x10kg, 2 x5kg
'100KG Bumper Plate Set' = 2x 5kg, 2x10kg, 2x 15kg, 2x20kg
'150kg Bumper Plate Set' = 2x 5kg, 2x10kg, 2x 15kg, 2x20kg, 2x25kg

The recommended set/bundle for the person mentioned above would be the 100kg bundle, as it gives plenty of possibilities for progression and will challenge the individual.

What Size Do I Need To Fit a Power Rack?

Most Power Racks measure 7ft or a little over 80" in width, enough to accommodate a minimum 7ft bar.
In order to safely rack a bar we recommend not to use a bar shorter than this, as you won't be able to load the sleeves.
