DESCRIPTION:
Use this tool to determine your onerepetition maximum weight ("onerep. max."), and percentages of that weight, for any weight training
exercise. Onerep. max. is the maximum weight for which you can do one repetition. For example, the most weight you can bench press one
time. It is widely used to measure overall strength and determine how much weight to use in many weight training programs. The
percentages calculated below are useful for estimating weight needed for each set.
To use this calculator, enter the maximum weight you can lift for ten
repetitions (ten times) in the first box on the left. This will calculate your onerep. max, then display 20 percentages of that below. Or, leave the first field blank
and manually enter a value for the second field to simply calculate percentages. All Weightmania tables can be
printed or copied to other applications like Excel. Rightclick for a speed menu with special options.
BUTTONS:
Calculate 
Calculates
your one repetition, maximum weight and displays 20 percentages of that weight in the table below. 
Clear 
Clears all
data input fields.

FIELDS:
Max. Weight (10 Reps.) 
Specifies
the maximum weight you can lift for ten repetitions (ten times) for a given exercise. If you already know your onerep. max.,
leave this field blank and enter it in the field on the right. When you select Calculate, this will display
20 percentages of that weight in the table below. 
OneRep. Max. Weight 
Specifies
your onerepetition maximum weight. To have Weightmania calculate this for you, leave this field blank and enter a value in
the first field, "Max. Weight (10 Reps)". When you select Calculate, this will determine your onerep. max., then display
20 percentages of that weight in the table below. 
Percentages 
In a table format, this specifies 20 percentages of your
onerepetition maximum weight above. For example, it shows 100 percent, 95 percent, 90 percent an so forth. These values can
be used to estimate how much weight to use for each set. This table can be can be copied to other applications like Excel. Rightclick
directly on it for for a speed menu with special options.
