What Bands Do I Need? A Beginner’s Guide to Band Types, Sizes & Tension Levels
If you’re new to resistance bands, one of the first questions you’ll face is also one of the most confusing: Which band do I actually need?
Bands come in different lengths, resistance levels, and use cases. To a beginner, they can all look similar—but they behave very differently once you start training.
This guide breaks down the main band sizes, what each one is best for, and how to choose the right tension so you can buy with confidence instead of guessing.
The Three Things That Matter When Choosing a Band
Before getting into specific sizes, it helps to understand what actually changes how a band feels during training.
Every resistance band decision comes down to three factors:
- Length – determines range of motion and versatility
- Tension range – how much resistance the band provides
- Use case – full-body training, accessories, or activation work
When these line up, bands feel smooth and predictable. When they don’t, workouts feel awkward or limiting.
The key idea here is matching the band to how you plan to train, not just how strong you think you are.
Full-Length Bands (41" & 37"): The Foundation for Strength Training
For most beginners, full-length bands are the best place to start. They allow natural movement patterns and scale well as strength improves.
41" Bands: The Most Versatile Option
41-inch resistance bands are considered the standard for full-body band training. They work well for pressing, pulling, squatting, hinging, and assisted movements.
They’re commonly used for:
- Squats
- Overhead presses
- Assisted pull-ups and push-ups
- General full-body workouts
- Barbell training (you will need pairs)
If you’re only buying one type of band, this is the safest and most versatile choice.
41” Resistance Bands — full-length bands for full-body strength training
37" Bands: Similar Feel, Slightly More Tension
37-inch bands behave similarly to 41" bands but generate tension a bit sooner because of their shorter length.
They’re often used when:
- You want more resistance in a shorter range
- Great for curls & chest press
- You already understand band setup and positioning
37” Resistance Bands — slightly shorter bands for higher tension sooner
Mid-Length Bands (32" & 20"): Targeted Strength and Accessories
As bands get shorter, they become more specialized.
32" Bands: Controlled Accessory Work
32-inch bands are commonly used for lower body movements (deadlifts or rows) accessory movements as well as controlled strength work.
Typical uses include:
- Chest presses with anchors
- Rows with limited range
- Deadlifts
- Users who are shorter and find that the 37" and 41" are too long
32” Resistance Bands — Lower body movements, high resistance resistance for accessory movements
20" Bands: High Tension, Short Range
20-inch bands generate tension very quickly and are best suited for short-range movements.
They are:
- Sold in pairs
- Slightly thinner than our other bands
- Great for upper-body accessory exercises, such as banded barbell shrugs.
- Good for banded shrugs, deadlifts with our footplate
What this means in practice is more intensity with less stretch—and less flexibility in exercise selection.
20” Resistance Bands — compact bands for short-range, high-tension work
12" Mini Bands: Activation, Stability, and Rehab
12-inch mini bands serve a very specific role. They’re designed for activation and stability, not full-range strength training.
They’re ideal for:
- Warm-ups and muscle activation
- Hip, glute, and shoulder stability
- Rehab-style or corrective exercises
They support your training—but they don’t replace full-length bands.

How to Choose the Right Tension Level
Band length determines how a band works. Tension determines how hard it feels.
A common beginner mistake is choosing resistance based on ego instead of control. Bands should challenge you without forcing sloppy movement.
A good starting guideline:
- You can perform 10–15 smooth reps, with 2-3 sets.
- The last few reps feel challenging but controlled, but not complete failure
- Technique stays consistent throughout the set
General guidance:
- Lighter tension for upper-body movements
- Moderate tension for lower-body exercises
- Increase resistance only once control feels automatic
In short: progression matters more than starting heavy.
So… What Should a Beginner Actually Buy?
If you want a simple answer, start with versatility.
For most beginners:
- A combination of 32", 37" and 41" bands should be your primary training tools
- 32" bands for deadlifts/lower body, 37" bands for curls, chest presses and 41" bands for squats and overhead movements.
- Add shorter mini bands later for accessories or activation
- Choose resistance based on control, not max effort
This approach removes confusion and lets your setup grow alongside your strength.
Final Thoughts: Buy With Confidence, Not Confusion
Resistance bands don’t need to be complicated. Once you understand band length, tension, and use case, choosing the right option becomes straightforward.
Remember:
- Longer bands = more versatility
- Shorter bands = more specialization
- Proper tension = better training quality
When your equipment matches your goals, training feels simpler—and progress follows.
