Rest may be the most suitable answer in the near term, but it is not a wise long-term strategy. Resting will only worsen your injury and make it harder for you to heal faster by putting unnecessary stress on already damaged muscles that need time off from lifting weights or other favorite activities while they repair themselves so we can get back at 100% sooner than if we exercised instead.
Exercise isn’t just good advice because of how much healthier everyone feels when exercising regularly, but it is necessary. Studies have shown significant improvement among those who follow an active lifestyle in that active individuals had lower blood pressure levels than inactive counterparts. Additionally, study after study shows that mild exercises like stretches could actually help you heal faster, build your muscles back up again, and get them to better shape than they were before.
