Custom optimization

(inspired by stronglifts)

This notebook shows features of streprogen, the Python strength program generator.

!pip install streprogen matplotlib --quiet

The default optimizer

program = Program(duration=4)

with program.Day():
    program.DynamicExercise(name="Squat", start_weight=100)

program.render()
print(program)

Customizing the optimizer

To customize the optimizer, change max_diff and max_unique below.

from streprogen import RepSchemeGenerator, RepSchemeOptimizer

program = Program(duration=4)


# Create a generator
generator = RepSchemeGenerator(
    max_diff=4,   # Maximum difference between two consecutive sets.
    max_unique=4, # Maximum unique sets in the solution.
)

# Override the default optimizer in the program
program.optimizer = RepSchemeOptimizer(generator=generator)

with program.Day():
    program.DynamicExercise(name="Squat", start_weight=100)

program.render()
print(program)
