FAQs

RESULTS & USE

Will this actually help me train tomorrow—not just “feel nice” tonight?
Yes—if you use it right. Do 30–60 seconds per muscle, light pre-workout (wake-up), moderate post-workout (flush). Most athletes notice easier warm-ups and less “cement legs” the next day. It won’t replace sleep or programming—it makes both work better.

Guns vs. foam rollers—do I still need both?
Different jobs. Roller = big surface sweep (IT band, back). Knotra = targeted knots (calves, quads, glutes) in minutes, without floor gymnastics. Many keep both. If you hate the floor, you’ll use Knotra more.

Is it too aggressive for shins, feet, or tender spots?
You control pressure and level. Start on Level 1–2 with the soft pad or ball head. Glide, don’t jab. If it feels “zingy,” back off. “Digs-in” is great for quads/glutes; be gentler on shins/plantar.

How long per area? How often?

  • Pre-workout: 10–20s per spot, total 1–2 minutes.

  • Post-workout or off-days: 30–60s per muscle, total 2–5 minutes.
    Daily is fine. More than 2–3 minutes on a single spot rarely helps.

Which head do I actually use?

  • Ball: general work (quads, glutes, hamstrings).

  • Flat: dense muscle / IT band sweeps.

  • Fork: traps (around the spine), calves/Achilles (straddle tendon).

  • Soft pad: sensitive zones (shins, plantar, forearms).
    You’ll get Runner/Lifter/Hybrid routine cards in the box. No guessing.

Can this replace a PT or massage therapist?
No. It’s a tool, not a diagnosis or manual therapy session. Use it to stay looser between sessions and make pro work go further.

How soon do I feel a difference?
Often immediately (less stiffness, easier range). Training carry-over shows up in the next warm-up—when legs feel usable instead of lead.

SAFETY & CLARITY

Where should I not use it?
Avoid the front/side of the neck and bony points (kneecap, spine bumps). Stay on muscle. If pain is sharp, electrical, or weird—stop.

Is there a “too much”?
Yes. Tingling, numbness, or more soreness = too much. Ease up, switch to a softer head, or shorten time.

What if I’m managing an injury?
Ask your clinician. As a rule, stay off acute injuries, open wounds, swelling, or recent surgeries unless cleared.

Heat, bruising, redness—is that normal?
Mild warmth/redness is common and fades. Bruising isn’t the goal—back off.

POWER, NOISE & SPECS (THE “REASON-WHY” PART)

Will this “bounce” off dense muscles like cheap guns?
We designed high stall-force so it keeps going under pressure on quads/glutes. Translation: it digs in instead of bouncing.

How loud is it?
Living-room quiet—you can use it while watching film or on the team bus. (We publish dB so you can compare.)

How heavy is it? Will my forearm die?
Built to be light enough for long sessions and awkward angles. If your previous gun felt like a kettlebell, you’ll feel the difference.

Do you publish real specs?
Yes: amplitude, verified stall force, noise (dB), weight, and real runtime. If we can’t verify it, we don’t print it.

COMPARISONS & FIT

I already own a roller/clamp/compression boots—why Knotra?

  • Roller: great for big sweeps; Knotra = quick, targeted knots.

  • Clamp (R8): awesome on calves; awkward elsewhere—Knotra fills the gaps.

  • Boots: relaxing compression; not tissue work—Knotra changes how muscle feels fast.
    Use what works—Knotra just gets you there quicker, without the floor.

I’ve tried budget guns—they were loud, heavy, and confusing.
That’s why we kept it quiet + light. Less gear, more guidance.

Mini vs. full-size—what should I pick?

  • Mini: travel/pre-workout wake-ups; smaller muscles.

  • Full-size: best for quads/glutes/dense tissue and daily recovery.
    If legs are your limiter, go full-size.

BATTERY, CHARGING & CARE

How long does the battery last?
Long enough for days of short sessions. We publish mAh and tested runtime at common levels.

Charging?
USB-C. Same cable as your phone/laptop (no mystery brick). From low to full typically takes a few hours.

Auto shut-off—annoying or helpful?
Helpful. It prevents overuse on one spot. If it stops, it’s reminding you to move on.

Cleaning & maintenance?
Wipe the body and heads with a soft, slightly damp cloth or alcohol wipe after sweat sessions. Don’t soak. Heads twist on/off for quick swaps.

PRICE, RETURNS & SUPPORT

Why not the brand-name Pro for $$$ more?
If you love it—great. We built Knotra for athletes who want quiet power, clear guidance, and verified specs without paying for marketing baggage.

QUICK START (because you’ll ask anyway)

  1. Before training: Ball head, Level 1–2, 10–20s each on calves, quads, glutes.

  2. After training: Flat/ball, Level 2–3, 30–60s each; soft pad for shins/feet.

  3. Never: front/side neck or bony points.

  4. Done in 3–5 minutes. Go live your life.

Still on the fence?
Read a routine card. Try one muscle for 30 seconds. If your next warm-up isn’t easier, send it back. We’re here to keep you training, not to win a gadget contest.
