Body-Solid G5B vs G6B: Which Home Gym Should You Choose?

Choosing between the Body-Solid G5B and G6B usually comes down to one main question:

Do you want the dedicated Pec Deck Station on the G5B, or do you want the Bi-Angular press system on the G6B?

Both machines are serious single-stack home gyms. Both start with a 210 lb weight stack and can be upgraded to 260 lb. Both can support lower-body attachments, rowing-style training, and pulley upgrades. But the training feel is different.

The Body-Solid G5B is the better fit if you want a strong traditional home gym with a dedicated pec station for chest isolation.

The Body-Solid G6B is the better fit if you want a more advanced pressing motion and a machine that feels closer to a premium strength station.

Quick Comparison: Body-Solid G5B vs G6B

Quick Answer

Choose the Body-Solid G5B if you want a serious home gym with a dedicated Perfect Pec station, strong exercise variety, and a slightly smaller footprint than the G6B.

Choose the Body-Solid G6B if you want the more advanced pressing experience. The Bi-Angular press arms are the main reason to step up from the G5B.

For most shoppers, this is not a weight stack decision. Both machines are strong there. It is a movement-quality decision.

Body-Solid G5B: Best for Perfect Pec Chest Isolation

The Body-Solid G5B is a strong choice if you want a serious single-stack home gym with dedicated chest isolation.

Its biggest feature is the Pec Deck Station. This gives users a more focused way to train the chest and rear delts beyond standard pressing.

The G5B is a good fit if you want:

• A 210 lb starting weight stack
• The option to upgrade to 260 lb
• A dedicated pec station
• Full-body selectorized training
• Attachment compatibility for leg press, inner/outer thigh, rower, and pulley upgrades
• A serious home gym without moving into a dual-stack machine

The G5B is not the entry-level choice. It is the machine for someone who already knows they want a more complete home gym and wants better chest isolation than simpler press-arm machines provide.

Why the G5B Features Matter

The G5B matters because it gives you a strong mix of traditional home gym training and dedicated isolation work.

Many home gyms can handle chest presses, pulldowns, rows, curls, triceps work, and leg extensions. The G5B adds a more complete upper-body setup because of the Perfect Pec station.

That matters if you care about chest development, shoulder balance, and a more complete feel during upper-body workouts.

The G5B is also easier to justify if you want a serious machine but do not necessarily need the more advanced Bi-Angular press design of the G6B.

Body-Solid G6B: Best for Bi-Angular Pressing

The Body-Solid G6B is the better choice if pressing movement quality is your main priority.

The standout feature is the Bi-Angular press arm system. Instead of feeling like a basic fixed press arm, the G6B is designed to guide the arms through a more natural pressing path.

The G6B is a good fit if you want:

• A 210 lb starting weight stack
• The option to upgrade to 260 lb
• Bi-Angular press arms
• A more premium pressing feel
• A heavier frame than the G5B
• Attachment compatibility for lower-body and cable training upgrades

The G6B is the stronger choice for buyers who care less about a dedicated pec station and more about the feel of pressing movements.

Pec Deck Station vs Bi-Angular Press: The Biggest Difference

This is the most important part of the comparison.

The G5B Pec Deck Station gives you a dedicated pec fly style movement. It is useful for chest isolation and rear-delt work. If you want more direct chest training beyond pressing, this is the G5B’s advantage.

The G6B Bi-Angular press arms are designed to improve the pressing motion itself. Instead of focusing on a separate pec station, the G6B focuses on making pressing feel smoother, more natural, and more advanced.

That means the better choice depends on how you train.

Choose the G5B if you want more isolated chest work.

Choose the G6B if you want a better pressing motion.

That is the real fork in the road. Everything else is secondary.

Weight Stack: Is There a Big Difference?

No. This is not the main deciding factor.

Both the G5B and G6B start with a 210 lb weight stack and can be upgraded to 260 lb.

That means both machines can work well for serious home gym users. Stronger users may eventually want the stack upgrade, especially for rows, presses, pulldowns, and leg training.

If you are comparing the two machines, do not choose based only on the weight stack. Choose based on the press system, footprint, and training style.

Footprint and Space: Which One Is Easier to Fit?

The G5B is slightly easier to fit.

The G6B is larger and heavier, so it makes more sense in a dedicated home gym space. The difference is not massive, but it matters if you are working with a tight room, basement, or garage corner.

Choose the G5B if space is a concern and you still want a premium single-stack home gym.

Choose the G6B if you have the room and want the stronger pressing experience.

Attachment and Upgrade Options

Both machines can be expanded with optional attachments and upgrades. In general, the main attachment categories are lower-body training, rowing-style movement, weight stack expansion, and pulley feel.

You do not need every attachment right away. The smarter approach is to choose the base machine first, then add attachments later if your training needs grow.

GLP Leg Press Attachment: Why It Matters

The GLP Premium Leg Press Attachment is the most important upgrade if you care about lower-body strength.

A built-in leg developer is useful for leg extensions and leg curls, but it does not replace a true leg press movement.

The GLP adds a more serious compound lower-body option for quads, glutes, and calves. For both the G5B and G6B, it is the attachment that most clearly expands the machine’s training value.

Important note: these machines typically use one side attachment at a time, so shoppers should decide between the GLP leg press and GIOT inner/outer thigh attachment based on their priorities.

GIOT Inner / Outer Thigh Attachment: Why It Matters

The GIOT Inner / Outer Thigh Attachment is more specialized than the leg press.

It can be useful for hip adduction, hip abduction, glute support, lower-body balance, and users who want more complete thigh training.

For most buyers, the GLP leg press is the better first add-on. The GIOT makes more sense if inner and outer thigh training is specifically important.

GROW Rower Attachment: Why It Matters

The GROW Rower Attachment gives the machine a rowing-style conditioning option.

This can be useful if you want a low-impact warm-up, conditioning between strength sets, or more variety without buying a separate rowing machine.

It is not essential for everyone, but it can make either machine more versatile in a smaller home gym.

SP50 Weight Stack Upgrade: Why It Matters

The SP50 Selectorized Weight Stack Upgrade increases training room for stronger users.

Since both machines start at 210 lb and can be upgraded to 260 lb, the SP50 upgrade is worth considering if multiple people will use the machine or if you expect to train consistently over time.

This upgrade matters most for larger movements like pressing, pulldowns, rows, and lower-body work.

GAP5 and GAP6 Pulley Upgrades: Why They Matter

Pulley upgrades are not the flashiest add-ons, but they affect the feel of the machine.

Smoother pulley movement can make rows, curls, triceps work, pulldowns, and cable movements feel more refined. If the machine will be used often, that smoother feel can matter.

For the G5B, the matching upgrade is the GAP5 Aluminum Pulley Set Upgrade.

For the G6B, use the matching GAP6 pulley upgrade if available with your configuration.

Which One Is Better for Serious Training?

The G6B is better if you care most about pressing performance.

The G5B is still a serious home gym, but the G6B has the more advanced press system. That makes it the better fit for someone who wants a premium pressing feel from a single-stack machine.

Choose the G5B if you want a strong machine with dedicated chest isolation.

Choose the G6B if you want the better pressing motion.

Which One Is Better for Chest Training?

This depends on what kind of chest training you mean.

The G5B is better for direct pec isolation because of the Perfect Pec station.

The G6B is better for pressing movement because of the Bi-Angular press arms.

If you want fly-style isolation, choose G5B. If you want a better press path, choose G6B.

When Should You Choose the G5B?

Choose the Body-Solid G5B if you want:

• A serious single-stack home gym
• A dedicated Perfect Pec station
• Strong chest isolation
• A slightly smaller footprint than the G6B
• A 210 lb stack with 260 lb upgrade potential
• A strong full-body machine without paying mainly for the Bi-Angular press system

The G5B is the practical choice if you want a premium home gym with better chest isolation and a strong overall value.

When Should You Choose the G6B?

Choose the Body-Solid G6B if you want:

• Bi-Angular press arms
• A more advanced pressing motion
• A heavier and slightly larger machine
• A premium single-stack home gym feel
• A 210 lb stack with 260 lb upgrade potential
• A better long-term option for users who care about pressing quality

The G6B is the stronger choice if the press system is the reason you are stepping up.

Final Recommendation

If you want the more advanced pressing experience, choose the Body-Solid G6B.

The G5B is the better fit for shoppers who want chest isolation and strong full-body training. The G6B is the better fit for shoppers who want a more natural, premium pressing motion.
