Stages of an Aerobic Workout
Long Term Plan
Beginning (4-6 weeks)
Progression (16-20 weeks)
The maximal force that a muscle
or group of muscles can generate
for one movement
The capacity to sustain repeated
Strength workouts build muscles
The heart’s right half pumps oxygen-poor blood to capillary beds in lungs. There, O2 diffuses into blood and CO2 diffuses out. The oxygenated blood flows into the heart’s left half where it is then pumped to capillary beds throughout the body.
Benefits of Strength Training the Body
Outer sheath of connective tissue muscle (toughened by strength workouts)
Bundles of muscle cells surrounded by
connective tissue (more connective
tissue develops from strength workouts)
Capillary bed before
Capillary bed after 8–12 weeks of strength workouts
(extra capillaries develop, circulation increases)
