When you start any new training method or supplement, it’s easy to feel like you’re improving. Energy feels better, legs feel snappier, and you’re not as sore. But feelings can trick us. The only way to know for sure that something is working is to measure it objectively. That’s where a baseline sports performance test comes in.

A baseline test is simply a repeatable workout or effort you perform before you make a change (like adding Extreme Endurance). You record hard numbers: time, watts, reps, heart rate, whatever is relevant to your sport. Then, after a set period on the new protocol, you repeat the exact same test under the same conditions. The difference between “before” and “after” is undeniable proof of progress (or lack thereof).

Extreme Endurance is particularly well-suited for this kind of testing because athletes consistently report reductions in lactic acid, less muscle soreness, lower cramping, and faster recovery – all things that show up dramatically when you push to your limits in a controlled test.

Below are three simple, sport-specific baseline protocols that thousands of athletes have used to prove the benefits of Extreme Endurance to themselves.

1. Cycling / Wattage Baseline (Indoor Trainer Test)

Best for: Road cyclists, triathletes, mountain bikers

Protocol:

Warm up thoroughly (15–20 minutes easy spinning + a few 30-second efforts).

Do a fixed-time effort: most people choose 10 or 20 minutes all-out.

Record:

• Average power (watts)
• Average heart rate
• Peak heart rate
• Perceived exertion (RPE) at the finish
• How your legs felt in the last 2 minutes (burning scale 1–10)

Take Extreme Endurance twice daily for 10 days (the time it takes to fully reduce exercise-induced acidosis), then repeat the exact same test at the same time of day, same warm-up, same trainer tire pressure, same fan setup.

Typical results athletes see: 8–25 watts higher average power at the same or lower heart rate, dramatically reduced leg burn in the final minutes.

2. Strength & Conditioning “80% Tri-Set to Failure” Baseline

Best for: CrossFitters, powerlifters, team-sport athletes, OCR racers

Protocol:

Choose three big compound movements you know well. Example used by hundreds of athletes:

• Bench Press @ 80% of 1RM
• Back Squat @ 80% of 1RM
• Weighted or strict Pull-ups (bodyweight if you can’t do weighted yet)

Test Day (Baseline):

• Warm up fully.
• With a running clock and no rest between movements:
• Bench press to failure → rack it → immediately walk to squat rack
• Squat to failure → rack it → immediately to pull-up bar
• Pull-ups to failure

Record total reps for each movement and total time from first bench rep to last pull-up.

Take Extreme Endurance for 7–10 days (most athletes see the strength-endurance effect fastest here), then repeat the same tri-set with the same loads.

Typical results: 15–40% more total reps and significantly faster completion time, with far less lactic “pump” and burn.

3. Running / Track Lactate Threshold Baseline

Best for: Runners, triathletes, hybrid athletes

Protocol:

• Warm up 15–20 minutes easy.
• Run 4–6 x 3 minutes at your absolute hardest sustainable effort with exactly 2 minutes easy jog recovery between reps.
• Record average pace or power (if using Stryd) for the hard efforts and average heart rate.
• Note how many of the intervals felt “under control” vs “dying.”

After 10 days on Extreme Endurance, repeat. Most runners drop 5–12 seconds per kilometer at the same heart rate and can maintain pace on the later intervals with far less perceived effort.

Why These Tests Work So Well With Extreme Endurance

Extreme Endurance isn’t a stimulant or pre-workout that gives you a temporary buzz. It works by reducing exercise-induced hydrogen ions and lactic acid buildup while improving oxygen utilization. Those mechanisms don’t always make you “feel” different on easy days, but when you push into the red zone during a hard baseline test, the difference is shocking.

Keys to Accurate Baseline Testing

• Same time of day
• Same warm-up
• Same nutrition and sleep the night before
• Same equipment and environment
• At least 48–72 hours of full recovery before each test
• Take photos/videos of the score sheet or bike computer – you’ll want proof when your numbers jump.

Do the baseline. Take Extreme Endurance exactly as directed for 7–10 days. Retest.

When you see the objective improvement with your own eyes, you’ll never train without it again.
