How long should I wear a weighted vest to maximize the benefits while ensuring safety and avoiding strain? Is there an optimal duration that balances intensity and endurance, or does it vary significantly based on individual fitness levels and goals? When considering the integration of a weighted vest into my workout routine, should I contemplate starting with shorter increments, progressively increasing the duration as my strength and stamina improve? Moreover, are there specific activities or exercises that lend themselves better to longer vest usage, or do certain forms of training warrant more cautious duration limits? Additionally, is there a point at which the added weight might become counterproductive, leading to improper form or unwanted fatigue? Should I also incorporate rest periods to allow for recovery while wearing the vest, and if so, how can I determine the ideal intervals between sessions? These questions seem pivotal for anyone looking to optimize their training regimen.
