How do you load 225 lbs on a barbell?

To load 225 lbs on a standard 45 lb barbell, load two 45 lb plates on each side: 45 lb bar + (2 x 45 lbs) + (2 x 45 lbs) = 225 lbs. In gym slang, this is referred to as 'two plates'.

How is 1RM (One Rep Max) calculated?

One Rep Max is estimated from submaximal sets (1 to 10 reps) using the standard Epley formula: 1RM = Weight × (1 + Reps / 30) or the Brzycki formula: 1RM = Weight / (1.0278 - 0.0278 × Reps).

Frequently Asked Questions

What is the color code for Olympic bumper plates?

The International Weightlifting Federation (IWF) standard: Red is 55 lbs (25 kg), Blue is 45 lbs (20 kg), Yellow is 35 lbs (15 kg), and Green is 25 lbs (10 kg). Change plates are White (11 lbs / 5 kg) and Black (5.5 lbs / 2.5 kg).

Should I always load the heaviest plates first?

Yes. Always slide the largest, heaviest plates closest to the barbell collar. This centers the mass, stabilizes the barbell whip during squats and clean & jerks, and prevents sleeve bending.
