To overcome fitness plateaus, individuals can try varying their workout routines, incorporating different exercise modalities, or adjusting intensity levels. For strength training, changing the number of sets, reps, or the amount of weight can stimulate progress. Incorporating cross-training can also engage different muscle groups, preventing adaptation. Proper recovery and rest periods are essential to allow the body time to adapt and build strength. Lastly, setting new, challenging goals can motivate continued progress and engagement.
