The Cold Plunge Stack

The Cold Plunge Stack turns a simple ice bath into a full recovery system. Start with the Ice Barrel 500 Bundle for a full-body cold plunge, support strength and long-term performance with Arnold’s Ultimate Stack from Momentous, and give hardworking muscles daily relief with the Hypervolt 2 from Hyperice. Built for people who train hard and want a clear, repeatable routine for feeling stronger, recovering smarter, and staying ready for whatever is next.

Why these go together

- **A full cold plunge ritual in one stack.** The Ice Barrel 500 Bundle, Arnold’s Ultimate Stack from Momentous, and the Hypervolt 2 work together so you have a clear sequence for recovery instead of piecing it together on your own.
- **Cold exposure that actually feels doable.** The Ice Barrel 500 is built for full-body immersion and comfortable sitting, so you can focus on your breath and time in the water rather than struggling with a cramped tub.
- **Proven performance basics, not fads.** Arnold’s Ultimate Stack leans on whey protein isolate, creatine monohydrate, Vitamin D3 (2000 IU), and Fiber+ to support strength, muscle function, bone health, immune support, and gut health.
- **Daily relief for tight muscles.** Hypervolt 2 is lighter and more powerful than the original Hypervolt, making it easy to reach sore spots around workouts or after a plunge.
- **For people who take training seriously.** This stack is designed for anyone who lifts, runs, or trains hard and wants a simple, repeatable way to recover and stay consistent.
- **Three specialists, one routine.** Ice Barrel focuses on cold therapy, Momentous on performance nutrition, and Hyperice on muscle relief, giving you expert support at every step of your recovery window.

How to use it

1. Set up and fill your Ice Barrel 500 Bundle, adjusting the water temperature and level to your comfort and experience.
2. About an hour before or after training, take the Momentous products from Arnold’s Ultimate Stack as directed on each label.
3. Ease into the Ice Barrel 500 for your planned cold plunge session, focusing on slow breathing and safe immersion time.
4. After you get out and dry off, use the Hypervolt 2 on tight or sore muscle groups for focused relief.
5. Repeat this routine consistently to build a recovery habit that matches your training volume and goals.

• Grass-fed Whey Protein Isolate
• Creatine Monohydrate
• Vitamin D3 (2000 IU)

**Cold Plunge Built For Daily Use**
The Ice Barrel 500 Bundle is designed as a high-capacity, ultra-insulated barrel that supports full-body cold therapy sessions. Its construction is made to feel stable and comfortable while you sit, so you can focus on breathing and session length.

**Targeted Muscle Relief Tool**
Hypervolt 2 from Hyperice is a handheld percussion massage device with multiple intensity levels. It is engineered with a rechargeable power system and interchangeable head attachments so you can target different muscle groups as needed.

Care & storage

Rinse and refresh the Ice Barrel 500 Bundle regularly, following the included guidance from Ice Barrel on water changes and cleaning so the plunge stays clear and comfortable. Set the barrel on a stable, level surface and use caution when entering or exiting, especially when the surfaces are wet.

Use Arnold’s Ultimate Stack from Momentous only as directed on each product label. Store supplements in a cool, dry place and keep containers tightly closed. Keep out of reach of children. If you are pregnant, nursing, taking medication, or have a medical condition, consult your healthcare provider before use.

Charge the Hypervolt 2 fully before first use and between sessions. Do not use the device in or near water, including while in the Ice Barrel or immediately after getting out if your skin is still dripping wet. Avoid using on broken skin or areas with reduced sensation. Stop use if you experience pain or discomfort that feels unusual.

Good product, minor issues

Overall I'm happy with this purchase. It does what it's supposed to do and the quality is good. Only giving 4 stars because the instructions could be clearer, but once I figured it out, everything worked perfectly.
