Working out is supposed to prevent injuries so that you can do those activities that require being fit; it should not cause injuries.
Place a brick on one shoulder; have a second brick thrown at the other shoulder. Both weigh the same, but one will land you in the emergency room. Same applies with exercise; explosive force

“Results showed that slower movement and fewer repetitions of exercises helped increase muscle mass in menopausal women which could aid future studies into the benefits of exercise as a treatment for menopausal symptoms.
These findings will be used to design specific exercise programs for everyday use to reduce the risk of injury and thus significantly contribute to a better quality of life in old age."
