When preparing to exercise, it's best to warm up your muscles before stretching. select the best answer from the choices provided. t f

Since there are no choices, I will just answer them based on a personal trainer's perspective. Muscles are best warmed up before stretching because they are already contracted and relaxed making movement in the joints more fluid. If an exercising individual performs a stretch when the muscles are cold, injuries are likely to happen. This is because the muscles are too cold and unprepared for the demanded movement. 

However, the on-going trend in the fitness industry these days is to know what are the two types of stretching activities. These are the active and passive stretches. Active stretch is best done BEFORE a work-out; this involves active movement of the joints and the whole body while performing a light stretch. Passive stretch is best done AFTER a work-out; this lessens the lactic build-up that occurs in the muscles after a physical activity.

Hello! i believe that it is okay, but you should limit on how much you go in a jacuzzi, hot tub, sauna etc. the rise in temperature may effect the development of you unborn baby and could cause some birth defects most likely in the first 3 months or 12 weeks of pregnancy. the recommended amount of time to be in a jacuzzi while pregnant would be 10  minutes or less.i hope this !
