La Crosse, Wisconsin, remote and virtual personal trainer.

Welcome to JKremmer Fitness – your source for science-backed protein reviews, weight loss strategies, and online fitness coach. Based in La Crosse, WI, I test, verify, and simplify the fitness industry one scoop at a time.

Latest Protein Review

I self-proclaimed myself on YouTube as the “Protein Review Guy” and you’re probably not looking for an online personal trainer. You’ve come to the right place for unbiased protein reviews. Here’s the list of my recent reviews. Thanks for visiting.

  • Kirkland Protein Powder vs Optimum Nutrition — Costco Value vs the “Legacy Brand” Scoop
    Kirkland Protein Powder vs Optimum Nutrition comes down to tradeoffs. Kirkland delivers budget efficiency and strong retailer protection. Optimum Nutrition offers better mixability, disclosed leucine, and a more structured quality framework. Neither provides batch-level receipts, but the higher score reflects performance consistency and measurable transparency where it matters.
  • Kirkland Protein Powder vs Ascent — Costco Value vs “Clean” Label Protein (Who Actually Delivers?)
    Kirkland Protein Powder vs Ascent comes down to value versus verification. Kirkland delivers lower cost per serving and higher volume, but keeps leucine proprietary. Ascent costs more, yet provides disclosed leucine, higher protein density, and formal sport certification. The better choice depends on whether price or transparency drives your decision.
  • Kirkland vs Transparent Labs: Bulk Value or Verified Leucine?
    In this Kirkland vs Transparent Labs comparison, I break down leucine disclosure, protein density, third-party verification, and real cost per scoop. Transparent Labs delivers published amino data and layered certifications, while Kirkland wins on bulk pricing and retailer protection. The tradeoff comes down to verified performance versus value.
  • Kirkland vs AGN Roots: Budget Blend or Fully Verified Isolate?
    Kirkland vs AGN Roots comes down to cost versus confirmation. Both deliver 25 grams of protein, but only AGN Roots publishes leucine content, amino data, and third-party protein verification. Kirkland wins on price and convenience, while AGN Roots wins on transparency and measurable muscle protein synthesis confidence.
  • How Is Kirkland Whey Protein? A Transparency & Quality Signal Breakdown
    How is Kirkland whey protein when it comes to transparency and verification? Many shoppers asking “how good is Kirkland protein powder” are really evaluating documentation, not just flavor or price. Kirkland participates in Informed Choice certification, but it does not publish a full amino acid profile, leucine disclosure, or batch-level COA data for independent review.

Starting Your Fitness Journey

Everyone wants to “start Monday,” but very few actually make it past week three. My approach strips out the gimmicks: no 30-day cleanses or “quick-burn” promises. This is about setting sustainable systems: habits, accountability, and recovery that outlasts motivation. Learn how to identify your true baseline and build upward from there.

Journey to Fitness and Health

Fitness isn’t separate from your life — it’s built around it. Here I cover realistic routines, running blocks, and nutrition setups that fit shift work, stress, and family life. The goal isn’t six pack shortcuts; it’s health span, longevity, and mental clarity. If you’re chasing long-term performance, this is your map.

Smart Nutrition Strategies

Protein timing, calorie control, and nutrient density — without the detox noise. I break down label transparency, slow-digesting proteins, and realistic food swaps. This is where you’ll find my deep dives into what’s actually worth spending one on. Start with examining my nutrition strategies to help you start with your weight loss goals.
