Giant sets sound like something made up by a bodybuilder who had too much pre-workout and not enough time: four or more exercises back-to-back with as little rest as possible between exercises.

Are they good for building muscle? Yes. Conditioning? Sure. Strength? Meeeeh.

In this article, I talk about everything giant sets, and how you can use them in your training:

What’s up! Have you heard people, even “experts,” tell you that creatine’s going to wreck your kidneys?

A new 2026 narrative review breaks down why you don’t need to worry about your daily scoop. Let me, in turn, break down what it found in an easy-to-understand way.

Myth: A High Creatinine Blood Test Means Your Kidneys Are About to Fail

When you use creatine, your body converts some of it into creatinine. That means a spike in your serum creatinine is a normal response to the supplement, not a sign of organ damage. If you need an accurate picture of your kidney health while you’re taking creatine, check your cystatin C levels instead, because they don’t get skewed by creatine.

Myth: Creatine Directly Damages Your Kidneys

A myth without any substance at all. The current scientific evidence clearly shows that taking creatine monohydrate at recommended doses does not cause kidney damage if your kidneys are healthy.

The (admittedly few) studies that have been done in people prone to kidney issues, like those with type 2 diabetes, haven’t found any impaired kidney function either.

Caveat: There isn’t enough research to say whether creatine is safe if you’re undergoing dialysis.

Myth: You’ll Turn Into a Water Balloon

Yes, you will gain water weight on creatine, but that’s a good thing. It ends up in your muscles, not under your skin, and well-hydrated muscles are high-performing and better-looking muscles.

And long-term creatine use doesn’t change your total body water relative to your muscle mass.

Myth: Get Ready for Kidney Stones

There is no evidence at all that creatine increases your risk of kidney stones.

Research shows it doesn’t even alter your urinary creatinine levels.

Myth: You Have To Cycle Creatine

Plenty of research confirms that staying on creatine is safe in healthy people.

The longest-term studies show that taking doses as high as 30 grams daily for 5 years causes no harm whatsoever.

Takeaway

The standard 5 grams of creatine per day is the most effective supplement for building muscle, strength, and high-intensity performance.

And it’s safe.

The posterior chain is the muscles on the back side of your body that extend your hips, stabilize your spine, generate power, and help you run, jump, hinge, and lift.

If your chest, arms, and delts are your show muscles, the posterior chain muscles are your go muscles. The ones you need for strength, posture, athletic performance, and injury prevention.

In today's article, I go through the 15 best posterior chain exercises in the StrengthLog app and why you should consider doing them.

And speaking of doing things, you'll also find two posterior chain workouts (also available in the app).

This Thursday, April 30, I’ll be hosting an AMA right here on r/strengthlog.

Location	Time Zone	Local Time
Stockholm	CET (UTC+1)	17:00
London	GMT (UTC+0)	16:00
New York	EST (UTC−5)	11:00
Los Angeles	PST (UTC−8)	08:00
Tokyo	JST (UTC+9)	02:00 (+1 day)
Sydney	AEDT (UTC+11)	04:00 (+1 day)

Ask me anything, and I’ll do my best to answer.

I have 30+ years of elite-level coaching experience, have designed many of the workout routines in the StrengthLog app (including programs for a wide range of sports), and have written close to 1,000 articles on strength training and nutrition over the years, both for print magazines (back when those were a thing) and for the StrengthLog website and its Swedish predecessor.

If you want to pick my brain about strength training, nutrition, programming, supplements, anything related to StrengthLog, or why not the really important stuff like video games and science fiction, come prepared with some good questions and stop by on Thursday.

You can also post them here beforehand, if you can't make it as it happens.

This will be the third StrengthLog AMA, and the last one was a big success. Let’s make this one at least as good.

Looking forward to seeing you on Thursday.
