👉Why Lean Muscle Matters

Lean muscle isn’t just about how you look — it’s about how you live. Maintaining lean muscle supports:

  • A healthier metabolism
  • Strength, mobility, and independence as you age
  • Bone density and joint health
  • Better blood sugar control
Muscle Up Bars are designed to help you build and maintain lean muscle, using high-quality whey protein your body can actually use. That’s why we don’t cut corners with fillers, sugar alcohols, or cheap protein sources.

👉 Fuel lean muscle. Support long-term health.

👉Why Muscle Up Bars Are Different

Most protein bars look good on the front of the label — until you flip them over.

Muscle Up Bars are designed to support lean muscle, recovery, and long-term health with ingredients your body actually knows how to use.

  • ✔ 16g of clean whey protein to support muscle repair and growth
  • ✔ Low sugar — fuel performance, not crashes
  • ✔ No sugar alcohols — easy on digestion
  • ✔ No maltodextrin or junk fillers
  • ✔ Soft texture, great taste — no chalk, no bricks
  • ✔ Simple ingredients you can read and trust

No gimmicks. No misleading claims. Just organic protein bars made with intention — designed to fuel your workouts, your day, and your long-term health. That’s what sets Muscle Up apart from the so-called best nutrition bars on the shelf.
👉 Fuel lean muscle the smarter way.

Real Reviews

What Our Customers Are Saying...

"Muscle-up bars are by far our top selling retail product. We literally have members who buy 1-2 boxes a week. I was skeptical about adding "another protein" bar to our store since RxBars had always done well for us. After tasting the difference it was a no brainer, the fact that they have more protein than sugar was an added bonus. These bars are one of a kind, our coaches and community absolutely love them and anytime I know I'll be away from the gym I make sure to pack a few for the trip."

Dan Gallagher - CrossFit Strongtown

Absolutely awesome bars!!

Armin W. - owner Udofit

High Quality Protein and Excellent Taste I really enjoy the taste of these bars. While they are not quite as high in protein as some other options on the market, they fell cleaner to me and I never have the bloating or digestive issues that Whey-based products sometimes cause.

John E. - Cary, NC

Great product and great customer service Highly recommend these bars! They are very tasty and are perfect if you are trying to eat “clean” as they have minimal ingredients unlike most protein bars. Customer service is also amazing! When I got my shipment, there was a hand written note from the owners thanking me for my business! I will definitely be ordering more!
