Why should cancer survivors avoid sudden increases in exercise intensity?

Cancer survivors should avoid sudden increases in exercise intensity because it can lead to injury and hinder their ability to stick with their exercise program. Following a cancer diagnosis and treatment, individuals may experience fatigue, decreased strength, and other side effects that impact their physical capabilities. Abruptly increasing exercise intensity can overwhelm their bodies, increase the risk of strains or sprains, and can also lead to feelings of discouragement, particularly if they are unable to maintain that intensity in the long run. A gradual increase in exercise intensity allows the body to adapt safely, facilitating consistency in the program and promoting sustainable fitness improvements over time.

The other choices do not align with the considerations necessary for the health and safety of cancer survivors. Quick improvements in fitness are not a primary focus for this population, as safety and long-term adherence take precedence. While burning more calories may be a goal in some contexts, it should not come at the expense of the individual's well-being or risk injury. Encouraging sudden increases in intensity does not align with the principles of safe exercise programming, which emphasize gradual progression to ensure that participants can remain active and engaged in their recovery and fitness journey.
