Deciphering the Planet Fitness Smith Machine Bar’s Weight

The Smith machine is a fantastic tool for isolating specific muscle groups and providing stability during exercises. Unlike free weight exercises where the barbell is completely unsupported, the Smith machine bar travels in a fixed, vertical or angled path. This controlled movement can be beneficial for beginners or when pushing to failure, as it reduces the risk of losing balance.

At Planet Fitness, the Planet Fitness barbell weight used on their Smith machines is consistently 35 pounds. This is a deliberate choice, likely made to be more accessible to a broader range of fitness levels. A lighter bar means that beginners can start with a manageable weight for exercises like squats, bench presses, and overhead presses, gradually adding weight plates as they get stronger.

Comparing Weights: Planet Fitness vs. Standard Barbells

It’s important to differentiate the Planet Fitness Smith machine bar from other types of barbells you might encounter. The weight of a gym barbell weight can vary significantly depending on its type and intended use.

Standard Olympic Bar Weight: A standard Olympic barbell, commonly used in powerlifting and Olympic weightlifting, typically weighs 45 pounds (approximately 20.41 kilograms). These bars are also longer and designed to withstand much heavier loads than a Smith machine bar. The difference of 10 pounds might seem small, but it can be noticeable when you’re used to one or the other.
Women’s Olympic Bar Weight: Women’s Olympic barbells are usually lighter, weighing 35 pounds (approximately 15.88 kilograms), similar to the Planet Fitness Smith machine bar. However, women’s Olympic bars are also typically shorter and have a narrower grip diameter.
Trap Bar Weight: Trap bars, also known as deadlift bars, can vary in weight. Some are around 45 pounds, while others are lighter. Their hexagonal shape allows for a different lifting biomechanic, often making deadlifts feel easier and safer for some individuals.
Fixed-Weight Barbells: Many gyms have sets of fixed-weight barbells, often called dumbbells or EZ-curl bars, that come in various increments. These are usually much lighter than Olympic bars and are used for isolation exercises or lighter compound movements.

Why Does Smith Machine Bar Weight Matter?

Knowing the precise weight of the Smith machine bar weight is fundamental for several reasons:

Accurate Tracking: To monitor your strength progression, you need to know your starting point and how much weight you’re lifting. If you don’t account for the bar’s weight, your recorded lifts will be inaccurate.
Program Design: Most training programs are designed with specific weights in mind. If you’re following a program that specifies reps and sets for a certain weight, you need to know the bar’s weight to add the correct plates.
Consistency Across Gyms: If you train at multiple facilities, understanding the weight of different equipment allows you to maintain consistency in your training. For example, if you’re used to lifting a 45-pound Olympic bar, you’ll need to adjust your mental calculation when using a 35-pound Smith machine bar.
Setting Realistic Goals: Knowing the bar’s weight helps you set achievable goals. If you aim to increase your bench press by 5 pounds, you know that adding a 5-pound plate to the 35-pound bar will get you to 40 pounds.

Fathoming the Mechanics of the Smith Machine

The Smith machine’s design is what differentiates its bar from a traditional free weight bar. The bar is fixed within two vertical metal guide rods, allowing it to move only up and down (or at a fixed angle in some models). This system is also equipped with a locking mechanism that allows you to “rack” the bar at various points by rotating it.

Benefits of the Smith Machine

The fixed path of the Smith machine bar offers several advantages:

Enhanced Stability: The guides eliminate the need to balance the weight, allowing you to focus solely on the muscle being worked. This is particularly useful for exercises like squats, where balance can be a limiting factor for beginners.
Reduced Risk of Injury: By preventing uncontrolled movements, the Smith machine can reduce the risk of dropping the weight or losing balance, making it a safer option for certain exercises or for lifters working with heavy loads.
Muscle Isolation: The controlled movement helps to isolate specific muscle groups. For example, in a Smith machine squat, your quads might be more engaged as the bar path is fixed vertically, reducing the range of motion for your glutes and hamstrings compared to a free weight squat.
Assistance for Beginners: New lifters can use the Smith machine to learn the movement patterns of exercises like squats or bench presses with less fear of injury.
Overcoming Plateaus: Sometimes, using the Smith machine can help break through plateaus in free weight exercises by allowing you to push past your limit with the added stability, or by focusing on the concentric (lifting) portion of the movement.

Limitations of the Smith Machine

While beneficial, the Smith machine also has limitations:

Unnatural Movement Path: The fixed path doesn’t always mimic natural human movement patterns. This can lead to less activation of stabilizing muscles and may not translate as effectively to real-world strength or sport-specific movements.
Reduced Core and Stabilizer Engagement: Because the machine provides stability, your core and smaller stabilizing muscles don’t have to work as hard. This can lead to imbalances if not supplemented with free weight training.
Potential for Joint Stress: For some individuals, the fixed, unnatural path can place undue stress on certain joints, particularly the knees or shoulders, depending on the exercise.
Bar Weight Discrepancy: As discussed, the lighter Planet Fitness barbell weight (35 lbs) means you’re lifting less than with a standard Olympic bar. If your goal is to train for powerlifting or strength sports that use standard equipment, you’ll need to account for this difference.

Integrating the Smith Machine into Your Workout

The Planet Fitness Smith machine can be a valuable addition to your training regimen. Here’s how to effectively incorporate it:

Exercises to Perform on the Smith Machine

The Smith machine is versatile and can be used for a wide range of exercises:

Squats: A staple for leg development.
Bench Press: Targets the chest, shoulders, and triceps.
Overhead Press: Focuses on the shoulders and triceps.
Rows: Can be used for bent-over rows to target the back.
Lunges: Provides stability for deeper lunges.
Calf Raises: Excellent for isolating the calf muscles.
Glute Bridges/Hip Thrusts: A stable way to load the hips.

Adjusting Weights for Smith Machine Exercises

When calculating the total weight for a Smith machine exercise at Planet Fitness, remember to add the 35-pound bar weight to the plates you load onto it.

Example: If you want to perform squats with a total of 100 pounds, you’ll load 65 pounds of plates (two 25-pound plates and one 10-pound plate, or other combinations) onto the 35-pound bar.
- 35 lbs (bar) + 65 lbs (plates) = 100 lbs (total)

This is crucial for logging your workouts accurately.

When to Use the Smith Machine vs. Free Weights

The decision to use the Smith machine or free weights often depends on your goals and current fitness level:

Beginners: Often benefit from starting with the Smith machine to learn proper form and build confidence before transitioning to free weights.
Muscle Isolation: If your primary goal is to isolate a specific muscle group, the Smith machine can be more effective due to its stability.
Reaching Failure: When pushing for maximum reps or aiming to go to failure, the safety provided by the Smith machine can be invaluable.
Strength and Power Development: For overall strength, power, and functional fitness, free weights are generally preferred because they engage more stabilizing muscles and mimic real-world movements.
Injury Rehabilitation: In some cases, a physical therapist might recommend the Smith machine for controlled rehabilitation exercises.

Beyond the Bar: Understanding Other Exercise Equipment Bar Weight

It’s not just the Smith machine bar whose weight you should be aware of. Knowing the weight of other exercise equipment bar weight can enhance your training.

Dumbbells: These are the most common free weight bar weight variations. They range from very light (2-5 lbs) to extremely heavy (over 100 lbs). Dumbbells offer independent arm movement, further challenging stabilizing muscles.
EZ-Curl Bars: Often used for bicep curls and triceps extensions, EZ-curl bars typically weigh between 10-25 pounds. Their curved shape is designed to reduce stress on the wrists.
Pre-loaded Barbells: Some gyms have sets of barbells with fixed weight plates permanently attached. These can range from 20 lbs up to 100 lbs or more, offering a convenient way to quickly grab a specific weight.
Adjustable Barbells: These are barbells where you can add or remove weight plates. A standard Olympic set with adjustable weight plates is the most versatile option for progressive overload.

The Concept of Adjustable Barbell Weight

The beauty of an adjustable barbell weight system, whether it’s a standard Olympic set or even a home gym Smith machine bar that allows for plate loading, is its scalability. You can start light and incrementally increase the weight as you get stronger. This is the cornerstone of effective strength training – progressive overload.

A home gym Smith machine bar will typically also weigh around 35 pounds, adhering to the common standard. However, the quality and durability can vary greatly depending on the manufacturer. When setting up a home gym, it’s essential to consider the load capacity and build quality of the entire Smith machine system.

Commercial Gym Bar Weight Standards

In a commercial gym bar weight, consistency is usually maintained. Most commercial gyms will have standardized Olympic bars (45 lbs) and Smith machine bars (35 lbs). While some may have variations, these are the most common figures. Understanding these standards helps you navigate different training environments smoothly.
