This study examined the effects of re-warm-up versus no before squat or bench press on mechanical, physiological, and psychophysiological responses in recreationally trained men. Twenty-two participants (23 ± 3 years) completed four randomized sessions involving different exercise sequences. Measurements included heart rate, blood lactate, tympanic temperature, perceived exertion. Key performance metrics such as mean propulsive velocity, peak power, velocity loss, effort index were analyzed. Findings revealed that re-warming up (W+BP+RW+SQ) significantly enhanced power compared to (W+BP+SQ) (p≤0.05; d=0.45-0.62). However, (W+SQ+RW+BP) did not improve mechanical standard sequence (W+SQ+BP) (p>0.05; d=0.10-0.38). Notably, loss higher third set under W+SQ+BP condition d=0.53-0.60). No significant differences physiological found between conditions. Overall, effectively improved when performed after but had minimal impact squats. These findings suggest lower-body exercises may enhance performance, while its benefits be less pronounced for upper-body exercises.
