What are Progress Lines?
What are Progress Lines?
We're the only resistance bands in the world with Progress Lines™ – which are numbered markers running across each band that show exactly where to hold or stand for hundreds of exercises.
This means no more guesswork and you can actually set up consistently and track your progress with individual resistance bands.
You're also never too far from your next challenge with up to 15 levels of measurable resistance on each Strong Band.
Clear levels = accurate set-up, more motivation and more progress! We're the first of its kind and proud to have a registered design 💁🏻♀️

General
Are resistance bands as effective as weights for building strength?
Are resistance bands as effective as weights for building strength?
They sure are!
Resistance bands:
- Provide variable resistance (more resistance when stretched further)
- Can be used in a range of different positions (standing, seated, lying) and do not rely on gravity like weights
- Can be a joint-friendly alternative to weights
- Allow training anywhere (great for consistency if you travel a lot!)
- Are incredibly versatile, opening up hundred of different exercises for your entire body
The issue people normally have when build strength with bands, is it’s difficult to set up consistently and track progress. This is why all our resistance bands have Progress Lines™ so you can consistently set up and see your progress.
Many of our customers use Strong Bands alongside gym training, while others use them as their primary strength tool.
Can you build muscle with resistance bands?
Can you build muscle with resistance bands?
Absolutely! When used correctly, resistance bands can build muscle just like weights.
The key is progressive overload – gradually increasing the challenge over time. Our Strong Band resistance bands are designed with our Progress Lines™ so you can measure your setup and increase tension consistently, instead of guessing.
Bands also provide variable resistance throughout the movement, which means the resistance level smoothly changes with your movement. This can be easier on joints while still challenging your muscles.

Over my 13 years of doing calisthenics no bands compare real rubber real quality fantastic people support and the only bands I seen with the markers for regression and progression the best in the market thanks Matt and Cy!
Really high quality material used. I've used this regularly all year and it still looks and performs as good as new. It's a really flexible piece of gym equipment that's proven to be incredibly useful in my recovery from a shoulder injury. It's a must have for any home gyms
I’ve been using this exercise band for a few weeks now, and I love it! It’s strong, comfortable, and perfect for both stretching and strength training. Great quality for the price — definitely recommend it for home workouts.
A Game-Changer for our Functional Training space.
As a gym dedicated to member engagement, progress, and building a strong community, we’re always on the lookout for tools that align with our mission to help every member become the best version of themselves. Matt and Cyan's Strong Band encompasses all of these values and we couldn't be happier to have their trio set in our clubs.
This resistance band set has been a fantastic addition to our functional training area. The quality is second to none; premium, durable construction, and an attention to detail that stands out. One of the most impressive features is the progress lines printed on each band, which allow our members to clearly track their improvement over time. It's a simple yet powerful feature that is exclusive to Strong Band!
But what truly sets this brand apart is their commitment to education and accessibility. They offer YouTube workout videos and a range of accessible programs and resources that our members can dive into, both inside and outside of the gym. This level of support makes these resistance bands not just a product, but a complete training solution that complements our coaching and helps deepen member engagement.
We’re proud to work with companies who share our passion for fitness, progress, and community - and this one absolutely delivers on all fronts. Highly recommended.
Excellent quality band. Having the markers is a real game changer, so tracking progress is so much easier!
I've been using Strong Bands since the day they were launched and little by little I've been moving onto different colour / strength bands .
I currently have some physical issues that restrict mobility and having the choice of band to assist me not only increases my strength it does so much for my confidence. I'm 67 yr old female and these bands are part of my daily routine either exercise at home or the gym .
Great bands, strong and practice. Can see these being a staple for a long time.
So happy with my new strong band ... and to have worked up from the yellow, to the pink and now grey band for some of my leg strengthening exercises !
Since I've started using the strong bands and following the tutorials and online videos I've improved so much on my body strength. It's been amazing!
Love all the bands. Great workouts included alongside this kit. This will be perfect for travelling.
Amazing piece of kit. Perfect for travel. I love the progression lines and the workouts included.
Great set to take me through the range of training. The bands are strong, don’t have a odour which might be important to some of you and extremely portable! Since purchasing the bands I’ve been away and taken some of them with me!
I am completely new to resistance training and I’m starting at the age of 60 I found the bands to be strong and the YouTube support excellent the communication with the team has been outstanding and I’m really pleased with my purchase so far. I am still learning, still getting into grips for the process and I’m sure it will be a while, but I was surprised that I am stronger than I thought I was, but I need to be consistent. The dedicated program and support provided so far I’m sure will help.
Quality product, love the door anchor that adds a lot more versatility.
Top product, free workouts provided, what more can you want. I ten pin bowl in a couple of leagues each week and these are a great support tool for me. If you're older like me and want to do some strength training without pumping iron at a gym. You know what you gotta do, just get some.
Love my strong bands, apart from routine based workouts, I use mine to take the tension out of being stuck behind a screen most of the day. Or, to relieve the stress of dealing with some of the idiots I encounter on a daily basis.
I use these with my PT clients - great quality bands and the progress lines are a stroke of genius!
These bands are exceptional. I take them everywhere I go - they're a great way to keep up my strength exercises for jogging. I can track my progress easily, and the bands themselves are excellent quality (love the design too). Would recommend!
We love our Strong Bands here at SAM Lab! The quality of the bands is fantastic, and we love how the colours pop in the gym. Thanks team!
I’ve been using the Strong Band exercise bands for a while now and I actually didn’t expect to like them as much as I do. I originally bought them for travel (took them with me to Japan) They’re super easy to pack and don’t take up space, which made it way easier to stay on track.
I use them most mornings to stretch and work on flexibility. They’re great for waking everything up without going straight into heavy training. I’ve also started swapping them in instead of weights sometimes just to mix things up.
They’re feel really durable. I’ve used cheaper bands before that roll up or have snapped after a couples workouts, but these feel solid. Comfortable to hold, good grip, and the resistance is actually strong enough to make it worth it.
I've used other bands before but what i love about Strongband is the markers this makes it really easy to progress your workouts and build strength as its clear where to hold the band. The bands are great quality, durable but also stretchy so they don't pinch ypu something ive suffered with other bands. A great product and one I would definitely recommend to others.
Amazing set! Quality and design of the product is by far the best I’ve seen and used. Extremely durable and great to have the measures of resistant to actually be able to track progress. I travel a lot and honestly this makes exercising and stretching much easier which has made me much more consistent, avoiding the feeling of falling out of routine. I bought the trio set and honestly glad I did, use the lime and pink bands for stretching whilst the pink and onyx for exercising depending on the muscle! Also fantastic to use for stretching before sport, for me I always use before golf or football! Highly recommend!!!!!
These bands are a game changer. They make strength training accessible for everyone and the amount of resources Strong Band give to their customers via their website and Youtube come as a real added bonus! These added details really help people who aren’t used to resistance band training get comfortable and active.
Incredible quality and amazing content and support!! Simply the best!
This band was just right for me for most exercises and I could easily swap for the pink band as I became stronger. It’s so easy to use and really versatile. I’m 75 and was very unfit and at first found lots of things difficult but because of the markings on the band I could increase my effort without a fuss. It can be used for every muscle group. The You Tube workouts are so easy to follow and Matt and Cy are really fabulous and so genuine.
Fantastic grading in strength/resistance between bands makes this a great and versatile set for your workouts. The segmented markings on the bands are something I've never encountered before on a resistance band and offer another way for you to increase resistance and progress while maintaining good posture.
I am always on the move for work and don't have access to weights or a gym most of the time, so these come with me wherever I go as a great alternative.
I was very lucky to be able to join Cy and Matt in their classes and progress from the lime band to the pink one and really see a difference in my fitness.
I have now been using the videos offered on the Strong Band You Tube channel to keep up my fitness and do a maximum of exercises with my Strong band.
I really recommend it as you can adapt the strength using the lines and it works for all ages !
This trio of bands, together with the free 8-week programme, has brought about the biggest change ever in my efforts to gain strength and change my body shape.
I had not used resistance bands before and had no idea how to, which made me feel a little uncertain. No need: the explanations from Matt and Cy on video are so clear, precise and encouraging that I got used to them very quickly and enjoyed improving my technique. It is ideal to be able to strength train with so much support but without the expense of joining a gym. Plus the bands are so easy to pack if you are going away and want to stay in your routine.
I find the daily reminders and recording stats incredibly motivating and have completely left behind the mindset of putting off exercise. I feel delighted to have found a method that works at my current level but will also guide my progression and offer variety. The best decision.
