Early strength gains in resistance training often occur within the first 1-2 weeks due to neurological adaptations rather than significant increases in muscle size. During this initial period, the body becomes more efficient at recruiting motor units, improving coordination and synchronizing muscle contractions. This leads to enhanced strength output even before physical changes in muscle tissue occur.

The adaptations include increased rate coding, which refers to the frequency of action potentials from motor neurons, and improved synchronization among motor units, which can increase overall force production. Therefore, it is primarily the nervous system that is adapting to the training stimulus at this early stage, allowing individuals to feel stronger and perform better without necessarily experiencing a corresponding increase in muscle mass.

As the training continues beyond this initial phase, more significant muscle hypertrophy and other adaptations will contribute to further strength gains, but the distinctive early improvements in strength are largely attributed to neural factors within the first couple of weeks.
