UNDERSUN FITNESS PRODUCT HIGHLIGHT: UNIVERSAL ANCHOR

Expanding your workouts to include more exercises and deliver maximum results often requires buying more bulky equipment and finding additional room in your house or gym bag for all the extra stuff. At some point, you run out of budget and space.

HOW TO BUILD BIG ARMS WITHOUT WEIGHTS

HOW TO BUILD BIG ARMS WITHOUT WEIGHTS

Anyone who says you can’t build big arms with resistance bands has never tried.

Your muscles don’t know the difference between resistance provided by a free weight versus a rubber band. A well-constructed set of bands provides all the tonnage you need – hundreds of pounds of resistance – to spark muscle growth in any body part, in this case, the arms.

The Undersun Tribe is your online support system for reaching your loftiest goals. Don’t worry, this isn’t some judgmental “cool kids” club. These are normal people – moms, dads, students, 9-to-5 workers – charting a new fitness journey, and they want you to join them.

For the past six months, I’ve been exclusively training with Undersun resistance bands and these bands are doing wonders for me! Thanks for making such a great product!

I love to be outside. Being able to take the Undersun Fitness bands anywhere, anytime is the true beauty of it. We get so stuck in our ways, thinking that you have to be in a gym lifting and throwing around a bunch of weights. I feel like the bands are easier on my joints and give me the same results.

What got me really sold on bands was when I started gaining muscle mass. I look back at pictures of me from years ago, and it's mind-boggling how skinny I used to be and how I look now. The bands have really played a vital role in being able to get me to where I want to be and continue to propel me.

When you have the bands with you, wherever you are, whatever you’re doing, you can literally work out there. It almost doesn’t matter where you’re at. I challenge anyone to come up with a place where you can’t work out with bands.

James Grage, Undersun Founder

I have been training in the gym over two decades now, but have recently been avidly and almost exclusively using the Undersun bands for about two months. I can honestly say that they’ve completely transformed my training regimen. I am able to target my muscles - via both compound and isolation movements - in ways I never before was able to at the gym. Specifically during the COVID 'lockdown' period, I have actually GAINED lean muscle and strength; I cannot wait to see just how much my body will react to this new and challenging training moving forward. Consider me part of the #undersuntribe for life!

Joe Ascanio

I give this program 5 stars for the results that it’s been giving me. It’s allowed me to keep and improve the shape I currently have while also being available for my wife and 3 girls. It gives me that pump that I need to feel like I’ve had the best workout and I can literally take it anywhere and any time. I’ve already gotten 3-4 of my friends on it as well. You will not be disappointed with this brand

Chris Maxwell

Going to the gym was never an easy thing for me to do. Since using the Undersun resistance bands, and the TA2 Bodyshock program, I've been more consistent in my workouts than EVER! Having the flexibility to train at home, outside, or while I'm traveling has truly been a game-changer for me over the last year and a half. Saying goodbye to the gym was the best decision I've made!

Emily West, Undersun Team Member

The Undersun resistance bands have been the unsung heroes of quarantine life! We’ve discovered so many amazing ways to challenge ourselves with these bands!

Ari Javadzadeh

Undersun Fitness Bands gave me the freedom to take my workout outside of the gym. And with the coronavirus affecting everyone and everything that is necessary in order to keep making progress. These bands are amazing and with the correct exercises they provide the same pump or even greater than some of the weighted exercises. Muscles can’t tell if your using a dumbbell or resistance bands, they just know there is resistance! From skeptic to believer, for sure!
