Walk into most commercial gyms and you'll rarely see chains hanging from a barbell. But chains have been a staple training tool for decades in powerlifting gyms, and collegiate or professional weight rooms. Chains are one of the most effective forms of accommodating resistance available. Whether your goal is increasing maximal strength, improving explosive power, building muscle, or refining technique, chains can provide benefits that straight weight alone cannot. At GritLab,

For decades, the weight room has been divided into two camps: heavy weights are for mass, and light weights are for "toning" or endurance. But if you’ve been following the latest literature, you know this thought has been crumbling for years. A landmark 2025 study (https://doi.org/10.1101/2025.04.28.650925) has provided the most definitive evidence yet: when it comes to hypertrophy, it's all about tension and how many reps you are from muscular failure. Comparable Strength an

Strength training often gets the spotlight in performance and fitness circles, and for good reason. Building strength improves resilience, preserves muscle mass, and drives performance across nearly every physical task. Specifically, " Absolute Strength " builds all other fitness qualities. But one of the most powerful health interventions available to nearly everyone doesn’t require a barbell, a gym membership, or even structured training. It simply requires walking . A larg

Most people treat the pull-up like a test instead of a lift. They jump up to the bar, try a few reps, fail, and assume they just “aren’t strong enough yet.” The problem is the approach. If you want to master your first pull-up, you need to train it the same way you would train a squat, bench press, or deadlift, which is by using a structured practice and progressive overload. Strength is built through consistent exposure to the movement combined with gradually increasing diff
