Purpose <p>We aimed to analyze and synthesize the evidence on resistance training warm-up and/or re-warm-up strategies and their effects on subsequent dynamic strength performance in strength-trained males.</p> Methods <p>We searched three electronic databases for original articles from inception to March 2025, with updates in November 2025. We included studies comparing the acute effects of various warm-up and/or re-warm-up strategies on dynamic strength performance, reporting outcome measures such as one-repetition maximum (1RM), barbell lifting velocity, power, total repetitions, or volume load.</p> Results <p>Nineteen studies focused on how resistance training warm-ups affect subsequent dynamic strength performance, while one study analyzed the effects of resistance training re-warm-ups on strength performance. The main findings show that (i) resistance training warm-ups increase 1RM loads in leg press and squat, (ii) using low relative loads in warm-ups lifted at maximal intended velocities optimizes peak power at 40% 1RM in the bench press, (iii) progressive-intensity warm-ups increase lifting velocity at 80% 1RM bench press and squat, (iv) warming up with loads ranging from 45% to 90% 1RM increases the number of total repetitions completed at 70%–75% 1RM in several strength exercises, and (v) a re-warm-up improves squat mechanical performance.</p> Conclusions <p>This review highlights the benefits of resistance training warm-ups on increasing 1RM load in lower-body exercises, peak power at light loads, propulsive velocity at heavy loads, and total repetitions at moderate loads. Nevertheless, a notable gap in research exists regarding re-warm-up strategies and their impact on strength performance, highlighting the need for further investigation.</p>
