Strength Benchmark Testing / 力量基准测试

Definition

Strength benchmark testing is the episode’s set of accessible proxies for maximum force: hand-grip dynamometry, a dead hang, a leg extension at body weight, and a half-body-weight goblet- or front-squat hold, each with a minimum and a good range.

Current Synthesis

Galpin starts from the simplest proxy, grip strength, and gives concrete thresholds rather than a single number: a minimum of about 40 kilograms for men and 35 kilograms for women, ideally above 60 kilograms, with less than 10% variation between hands. He notes that the non-dominant hand is often stronger, so the comparison is between hands rather than against handedness.

For the lower body he prefers a leg extension over a back squat for average people because it is standardized and not technically demanding, with a target of body weight that drops about 10% per decade after age 40, and with repetition-conversion equations that can estimate a one-rep max when fewer than about five reps are used. A front squat or goblet squat hold is the alternative: about half body weight held at the bottom position for roughly 45 seconds, with beginners starting at one-third of body weight for 30 seconds. Two caveats matter more than the numbers: do not test to maximum without comfort in the technique, and standardize the warm-up so results remain comparable across testing weeks.

Key Claims

• Grip strength is the cheapest strength proxy, with roughly 40 kg and 35 kg as minimums for men and women, above 60 kg as an ideal, and less than 10% between-hand variation.
• A dead hang of at least 30 seconds is treated as a minimum, 30 to 50 seconds as good, and above 60 seconds as generally satisfying, while the standard scales imperfectly with body weight.
• A leg extension at body weight is preferred over a back squat for average people because it is standardized and technically undemanding, with about a 10% per-decade decline after age 40.
• A half-body-weight goblet- or front-squat hold for about 45 seconds tests strength together with position, core strength, and low back stability.
• Technique comfort and a standardized warm-up are preconditions for meaningful or safe maximal strength testing.

Evidence

• Grip thresholds: Essentials: How to Assess & Improve All Aspects of Your Fitness | Dr. Andy Galpin describes a hand grip dynamometer costing roughly $20 to $100 and gives minimums of about 40 kilograms for men and 35 kilograms for women, ideally above 60 kilograms with under 10% between-hand variation.
• Dead hang: Essentials: How to Assess & Improve All Aspects of Your Fitness | Dr. Andy Galpin sets a 30-second minimum, 30 to 50 seconds as good, and above 60 seconds as generally satisfying while noting the standard scales imperfectly for very heavy or very light people.
• Leg extension preference: Essentials: How to Assess & Improve All Aspects of Your Fitness | Dr. Andy Galpin prefers a leg extension over a back squat for average people because it is standardized and not technically demanding, with a body-weight target declining about 10% per decade after 40.
• Squat hold: Essentials: How to Assess & Improve All Aspects of Your Fitness | Dr. Andy Galpin suggests holding about half body weight at the bottom for roughly 45 seconds and one-third of body weight for 30 seconds for beginners.
• Caveats: Essentials: How to Assess & Improve All Aspects of Your Fitness | Dr. Andy Galpin warns against testing to maximum without technique comfort and requires a standardized warm-up for retesting.

Counterevidence & Qualifications

These are public benchmark heuristics, not clinical norms, and the episode itself flags several of them as body-size dependent or technique dependent. Grip and dead-hang standards are distorted by body weight and hand size, repetition-conversion equations are estimates, and goblet-hold performance depends on mobility, limb proportions, and experience as much as on strength, so results are best read against a person’s own prior tests rather than as universal cutoffs.

What Changed

• Added the accessible strength benchmarks, their thresholds, and the technique and warm-up conditions attached to them.
