Planet Fitness Smith Machine Bar Weight (Quick Answer)

The Smith machine bar at Planet Fitness usually weighs:

20–25 lbs (9–11 kg)

This depends on the equipment manufacturer used in the gym.

Typical machines include:

• Hammer Strength models: about 20 lbs (9 kg)

Unlike a traditional Olympic barbell, Smith machine bars often include counterbalance systems, which make the effective weight feel lighter.

Why the Planet Fitness Smith Bar Is Lighter Than a Standard Bar

A standard Olympic barbell weighs 45 lbs (20 kg). Smith machines are designed differently to improve accessibility and safety.

1. Built-In Counterbalance System

Many Smith machines include internal counterweights that offset part of the bar’s mass.

Benefits:

• Easier starting weight

• Better control for beginners

• Reduced joint strain

This design helps users perform exercises like:

• Squats

• Bench presses

• Shoulder presses

• Lunges

without needing a spotter.

2. Guided Rail System Improves Stability

Smith machines move along fixed vertical rails, which removes the need to stabilize the bar.

Advantages include:

• Lower injury risk

• Better form for beginners

• Controlled movement patterns

Because stabilization isn’t required, the bar doesn’t need to be as heavy as a free barbell.

3. Planet Fitness Focuses on Beginner-Friendly Equipment

The entire equipment selection at Planet Fitness is designed to support their “Judgment Free Zone” philosophy.

A lighter bar helps:

• First-time lifters feel comfortable

• New members learn proper form

• Casual gym-goers avoid intimidation

For many people starting strength training, lifting a 20-lb Smith bar feels far more approachable than a 45-lb Olympic bar.

Why Knowing the Smith Machine Bar Weight Matters

Understanding the bar weight is important for accurate workout tracking.

For example:

If you add:

• 45 lb plates on each side (90 lbs total)

• Smith bar weight = 20 lbs

Your total lift = 110 lbs

Many beginners forget to include the bar weight, which can make progress tracking inconsistent.

Tracking correctly helps with:

• Strength progression

• Workout planning

• Setting realistic goals
