How do you calculate predicted 1RM?

Calculating 1RM

1. Multiple the number of repetitions you can perform on an exercise to failure by 2.5, for example, a load you can lift 10 around.
2. Subtract that number from 100 to determine the percentage of your 1RM.
3. Divide the above number by 100 to get a decimal value.

What is the formula for 1 rep max?

Work Out Your Weight For your upper body, find the heaviest weight you can lift 4-6 times and plug it into this equation: (4.6RM X 1.1307) + 0.6998. So if you can do 5 reps of 60kg, then according to the formula – (60 x 1.1307) + 0.6998 – your 1RM will be 68.5kg.

What is the brzycki equation?

The Brzycki (1993) equation is as follows: Weight ÷ ( 1.0278 – ( 0.0278 × Number of repetitions ) )

How does the Epley 1 rep max formula work?

The Epley 1 Rep Max Formula calculator computes the one repetition max using the Epley formula, the weight lifted and the number of repetitions. One Rep Max (RM): The calculator returns the One Repetition Maximum in pounds. However, this can be automatically converted to other weight units (e.g. kilograms) via the pull-down menu.

Which is the most accurate formula to calculate your 1RM?

There are many different formulas to estimate your 1RM, all with slightly different calculations. The most popular (and proven accurate 1) one is the Brzycki formula from Matt Brzycki: weight / (1.0278 – 0.0278 × reps) If you just managed to lift 100 kg for five reps, you’d calculate your 1RM like this:

How to calculate 1RM in 1 rep max?

1 Brzycki: 1RM = W x (36 / (37 – R)) 2 Wathan: 1RM = (100 x W) / (48.8 + (53.8 x e-0.075 x R)) 3 Lander: 1RM = (100 x W) / (101.3 – 2.67123 x R) 4 Epley: 1RM = W x (1 + 0.0333 x R) 5 Lombardi: 1RM = W x R0.1 6 Mayhew et al.: 1RM = (100 x W) / (52.2 + (41.9 x e-0.055 x R)) 7 O’Conner et al.: 1RM = W x (1 + 0.025 x R)
