A Life Fitness functional trainer is the centerpiece of many commercial gyms and health clubs, and there’s no reason why that can’t be the case for your home gym as well. Not only are these machines great for functional training purposes, but they can also replace multiple pieces of gym equipment due to their versatility. 

There are two main Life Fitness functional trainers available for home gym owners: The Life Fitness G7 Home Gym and the Signature Series Dual Adjustable Pulley. There are some other home gym options available on the brand’s website, but for today we’re going to focus on these two cable machines.

We’ll let you know what we like about each one, and who we see as the target audience for both.   

Giving Your Fitness Equipment Shopping a New Life  

We’ve done a dizzying amount of strength training equipment reviews. From testing the best Olympic barbells and adjustable dumbbells, to taking just about every exercise bike on the market for a spin, you could spend the better part of a day just reading every review on here. 

But nobody has time for that, which is why we condense many of our reviews to give you a quick snapshot of everything you need to know before heading to checkout.

Life Fitness G7 Home Gym

Fly Like a G7

Life Fitness G7 Home Gym

If you’re looking for a high-end functional trainer that enables a full-body workout from the comfort of your home, the Life Fitness G7 Home Gym could be a valuable investment. Featuring 160-pound dual weight stacks, a 2:1 pulley ratio, 20 height positions, and a variety of included attachments, the G7 enables you to perform a seemingly endless amount of exercises. Whether you’re looking to work on small, stabilizing muscles, target specific muscles with fixed motion exercises, or perform a full-body functional workout, the G7 has you covered.The G7 comes with a pair of medium-length soft strap ergonomic handles, a foot strap, thigh strap, straight bar, and exercise ball. And, since it uses a traditional carabiner for attachments, you can easily build out your gym with various attachments. The machine comes equipped with a multi-grip pull-up bar that allows for three different hand positions. Cable motion technology enables user-defined paths of motion so it can be used in virtually any position.Costing close to $3,700, the G7 is certainly an investment. Additionally, it stamps out a rather large footprint. Measuring 48.5 inches long, 69.5 inches wide, and 83 inches high, Life Fitness recommends an area of 10 feet by 8 feet to house the machine. While the full weight of the machine is not specified, we know this thing is heavy . You want to be sure you have the space for it as well as the ceiling clearance before making this purchase.

Pros: 

  • Comes with multiple attachments  
  • Lifetime frame warranty
  • Made with commercial-grade materials

Cons:

  • Total cost is around $4,500 after shipping (though financing plans are available) 
  • You need a floor space of at least 10’ L x 8’ W (still relatively compact for a functional trainer) 
  • Effective resistance tops out at 80 pounds

The Life Fitness G7 Functional Trainer is a great pick for those who want a commercial-grade piece of equipment in their own home gym. Right off the bat, we have to warn you that this costs around $4,500 after shipping and handling, and if you want white glove installation service, you’re going to have to pay even more. 

sam using life fitness functional trainer g7 home gym

But, here are a few of the reasons why we think it’s worth it. For one, you’re getting a premium functional trainer made with top-of-the-line materials such as an 11-gauge steel frame, buttery-smooth pulleys, and durable cables. The frame and pulleys are backed by a lifetime warranty, and the cables are covered for three years (which is the industry standard). 

There’s also an option to add an adjustable bench to your order, which can increase the amount of moves you can do with the G7. If you want another commercial-grade bench, we recommend checking out the Hammer Strength Adjustable Bench.

You’ll get a dual 160-pound weight stack that has a 2:1 ratio, meaning the effective resistance only goes up to 80 pounds (unfortunately, Life Fitness’ 50-pound weight stack upgrade is not compatible with the G7). That’s not a lot of weight, but it’s enough for the type of moves you’ll do with a functional trainer. 

This type of functional trainer isn’t the best if you’re someone who likes to utilize moves like lat pulldowns during your training sessions, but you do get a split-grip pull-up bar to help you use your bodyweight on back day.  

Life Fitness Signature Series Dual Adjustable Pulley

Life Fitness Signature Series Dual Adjustable Pulley
Life Fitness Signature Series Dual Adjustable Pulley

Life Fitness Signature Series Dual Adjustable Pulley functional trainer is certainly a big investment, but one that offers users plenty of exercises with just one machine. Featuring two 390-pound weight stacks, a 4:1 pulley ratio, 22 height adjustments, three pull-up bar grips, and several attachments, this functional trainer is versatile.The cable motion technology encourages high-speed movements with user-defined paths of motion for a personalized workout. With almost 12 feet of cable length, you can also perform traditional fixed strength movements, full-body functional training, or stability and mobility work. If you’re new to strength training, this Signature Series functional trainer may be a good option as the resistance begins at a light weight. In fact, each weight stack only has 97.5 pounds of potential user resistance so if you’re looking to lift heavy, this may not be the trainer for you.Included in your purchase is a pair of medium-length soft strap ergonomic handles, a foot strap, thigh strap, straight bar, and an exercise ball. The carabiner attachment system is universal so you can continually grow your gym with new attachments. Keep your space organized with the six accessory storage hangers built into the Signature Series Adjustable Pulley trainer.The Life Fitness Signature Series Dual Adjustable Pulley functional trainer comes with a price that will be overwhelming to most. It also takes up a good amount of real estate in your home gym with a footprint measuring 45 inches long, 62 inches wide, and 94 inches high. More importantly, Life Fitness recommends an area of 217 inches long, 410 inches wide, and 112 inches tall, which is not the kind of space most consumers have at home. Before making this purchase, be sure that there is plenty of space for this tank of a machine to reside.

Pros: 

  • Multiple chin-up handles
  • Best option for maximum cable motion 
  • Available in two color options

Cons:

  • Total cost can near $10,000 (or $231 per month with Affirm)  
  • Complicated assembly (white glove installation costs extra) 
  • Utilizes 4:1 pulley ratio, meaning pulling 100 pounds only gives you 25 pounds of resistance 

The Life Fitness Signature Series Dual Adjustable Pulley Functional Trainer would be our choice for people who run a personal training studio out of their home gym. 

You get six chin-up handles, multiple accessories, cable travel distance of nearly 12 feet, and a lifetime warranty on all parts but the cables (which are covered for three years). There’s dual 390-pound weight stacks that come with a 4:1 pulley ratio (and optional shrouds if you want extra protection), which can be a good or a bad thing depending on what type of training you’re looking to do.

The increased ratio means you’re getting less tension on the stacks, so pulling 390 pounds really only feels like 97.5, which is only slightly more than you get with the G7. On the other hand, you’re getting a longer cable travel, which can be good to replicate suspension training. 

After shipping and handling, the price of this functional trainer could be near the $10,000 mark, and that’s before adding on any additional machines (Life Fitness says people often buy this and a linear leg press in the same order). But, people are apparently buying it frequently as the company warns there may be a 22-week wait time on this product.

Which Life Fitness Functional Trainer Should You Buy?

Firstly, we should say that while we love functional trainers, there are some people who should put them at the bottom of their priority list. That would include people who have sport-specific training goals (such as powerlifters or CrossFitters), very heavy lifters, and those in compact spaces. 

If you don’t fall into any of those categories and are still interested in a Life Fitness Functional Trainer, here’s who we think should go with the G7 and who would probably be interested in the Signature Series Dual Adjustable Pulley. 

Who Should Buy the Life Fitness G7 Home Gym: 

  • Those looking for a relatively compact functional trainer 
  • Anyone looking for a versatile functional trainer 
  • Home gym athletes who don’t plan on lifting heavy weights

Who Should Buy the Life Fitness Signature Series Dual Adjustable Pulley: 

  • Those who run a personal training studio  
  • People who are looking for the best-of-the-best
  • Anyone who wants a functional trainer with longer cable travel

Financing, Warranty, Returns

Both the Life Fitness G7 and the Life Fitness Signature Series Dual Adjustable Pulley have financing plans available through Affirm. You can check to see if you pre-qualify at checkout. 

Both machines have a limited lifetime warranty on the frame, welds, and pulleys, and have a three-year warranty for the cables (the industry standard). 

Life Fitness gives you 30 days from the date of delivery to return all strength training and cardio equipment, minus a 20 percent restocking fee. Every item must be in its original box. 

Customer Reviews

The Life Fitness G7 Home Gym has a 4.8 average rating with 42 total reviews, 36 of which are 5-star ratings. 

The lone one-star review seems to come from someone who didn’t even purchase the product. 

The Life Fitness Signature Series Dual Adjustable Pulley has no customer reviews as of this writing. 

Final Verdict of Our Life Fitness Functional Trainer Reviews

Life Fitness functional trainers may not be the most versatile machines on the market (they don’t come with a Smith machine, like the Force USA G20 All-in-One Trainer), but there’s a reason why you spot them and their other brands (like Hammer Strength and Cybex) all over the world—because they’re built to last. 

These would be the functional trainers we’d recommend to anyone who’s looking for a heavy-duty piece of equipment that works for most trainees. After all, if they can last while being used by hundreds of people per day, there’s no doubt they’ll be a mainstay in your home gym for many years to come.
