ZINGO® Pre-Workout Edge

Fast, fixed-dose caffeine for strength, power and training output

A lot of pre-workout products make caffeine messy. Recent resistance-training studies using 3 mg/kg caffeine have shown meaningful improvements in power, bar speed and muscular endurance. ZINGO® gives you a cleaner, simpler way to plan that intake before training.

Why it's an edge

Recent resistance-training studies at 3 mg/kg show benefits in strength, power, velocity and muscular endurance. That makes ZINGO® a strong fit for gym users who want fast, fixed-dose caffeine without a can, shaker or sugar load.

Pre-workout intake isn't only about quantity — it's about timing, convenience and consistency. A pouch designed for rapid oral release fits the warm-up window better than a drink that needs to be brewed, mixed, or sipped slowly.

Why timing matters before training

ZINGO® is designed for rapid oral release, which makes it more useful when the window between getting to the gym and starting your first working set is shorter than you'd like.

⏱

Built for pre-workout timing

Useful for gym sessions, group classes, runs or lifts where you need caffeine available by the time you're under the bar.

🎯

No can, no shaker, no sugar

No powders, no mixing, no liquid volume sloshing in your stomach. Just a fixed dose in a pouch you can carry in any kit bag.

What it can support in the gym

Strength

Strength & power

• Support for bar speed & power at moderate-to-heavy loads
• Useful for lifts where output and intent matter
• Stronger lower-body effects in recent studies

Endurance

Session quality

• Support for muscular endurance within the session
• Helpful for getting more from working sets
• Can help offset lower early-day training quality

Format

A cleaner pre-workout caffeine

For gym users who want planned, fixed-amount caffeine rather than a huge powder stack. Predictable dose, no guesswork, no clean-up.

Evidence snapshot

Recent resistance-training research, especially studies using 3 mg/kg caffeine in trained lifters.

2024

Resistance-trained men and women: 3 mg/kg caffeine improved squat velocity and power by 2.5% to 8.5%, and muscular endurance measures by 3.0% to 8.9%.

2025

Resistance-trained men: 3 mg/kg caffeine improved strength, power and endurance performance, and helped offset lower morning training performance at some loads.

2023

3 mg/kg caffeine improved strength, power and endurance, with stronger effects at higher loads and in lower-body work like the back squat.

2021

3 mg/kg before sessions improved performance adaptations across a wider range of loads in bench-press training, even though 1RM gains were not greater than placebo.
