Research has firmly established strength and resistance training benefits for your physical and mental health. Lifting weights may be the first thing that comes to mind when thinking about strength training. This can also include using resistance bands, kettlebells, and body-weight exercises like pushups, pull-ups, or squats. Even activities like plyometrics and yoga can be considered strength training. Although there is a lot of research on exercise during pregnancy, there are limited studies on strength training. ACOG attributes the lack of literature to resistance training not being considered a safe activity in early guidelines for exercise during pregnancy. This was due to potential injury and possible fetal heart decelerations. This article examines the evidence on strength training, physical changes that can affect strength training, and precautions and tips to make your workouts safe during pregnancy.
