Kuhusu kifaa hiki cha kupigia hesabu
A one-rep-max (1RM) calculator estimates the most weight you could lift for a single repetition from a set you actually performed. It uses the Epley formula (1RM = w × (1 + reps/30)) by default, with Brzycki, Lombardi and O’Conner as alternatives, and prints a table of training loads at common percentages of your max.
Say you squat 100 kg for 5 clean reps. Epley estimates 100 × (1 + 5 ÷ 30) = 100 × 1.167 ≈ 116.7 kg, while Brzycki gives 100 × 36 ÷ (37 − 5) = 112.5 kg. The two agree closely for sets of about 2–10 reps and drift apart on very high-rep sets, which is why the tool shows several formulas side by side.
From the estimated max it builds a percentage table so you can program training loads — for example roughly 85% for a hard triple, 70% for hypertrophy work. Estimating a 1RM from a moderate set is safer than testing a true single, especially without a spotter, and lets you set weights without maxing out every session.
Maswali yaliyoulizwa mara nyingi
Basi huwaje mkapanda mmoja?
From a set you completed. The Epley formula is 1RM = weight × (1 + reps ÷ 30); Brzycki is weight × 36 ÷ (37 − reps). Both are accurate for about 2–10 reps and diverge for very high-rep sets.
Why show percentages of my 1RM?
Strength programs prescribe loads as a percentage of your max — for example 5 reps near 85% or hypertrophy work around 70%. The table converts your estimated 1RM into those working weights.
Je, ni afadhali zaidi kupima kiwango cha juu kuliko kujaribu kiwango cha juu zaidi?
Kwa kawaida, 1RM kutoka katika kikundi cha wastani huepuka kujeruhiwa na mtu wa kweli, hasa bila doa au uzoefu.
Ninapaswa kuinua kiasi gani cha magurudumu 5?
Roughly 85–87% of your 1RM. The training-load table converts your estimated max into a weight for each percentage and estimates the reps each load allows using the Epley relationship.
Ni kanuni gani ya 1RM iliyo sahihi zaidi?
All are estimates and none is exact. Epley and Brzycki agree closely from 2–10 reps and diverge at higher reps; the tool shows Epley, Brzycki, Lombardi and O’Conner so you can compare them for your set.
Ninapaswa kujaribu tena sheria yangu mara ngapi?
Every 4–8 weeks is typical, or simply recalculate from a hard set whenever your working weights climb. Estimating from a rep set avoids the fatigue and injury risk of frequent true-max attempts.
Je, hilo lafanya kazi kwa kila mhuri?
It works best for barbell lifts like the squat, bench press and deadlift where you can perform a controlled set of 2–10 reps. It is less reliable for isolation exercises and very high-rep endurance sets.
