What is a likely outcome of not allowing sufficient rest between training sessions?

Insufficient rest between training sessions can lead to decreased strength and an increased risk of injury. When the body does not have adequate time to recover, fatigue can accumulate, reducing the muscles' ability to generate force. Overtraining can also inhibit the body's natural repair processes, leading to muscle wear and increased susceptibility to strains or other injuries.

Moreover, recovery is essential for muscle growth and performance, as it allows the body to repair and rebuild tissues that have been stressed during workouts. Without sufficient rest, the effects of overtraining can include decreased performance levels, increased cortisol levels, and potential burnout. These factors collectively underscore the importance of allowing adequate recovery time in a training program.
