During pregnancy, mothers should be extremely careful about the type of exercises that they opt in for at a workout. For the second trimester, exercises which are done with weights help a lot in building up leg muscles, the glutes and the entire core of expectant mothers. Popular exercises include “Ballerina” and “Wide squat pull.” Ballerina can be done with weights but for beginners and people with problems in the aforementioned areas, it should be done with resistance bands. This will help maintain a good form. Squat and Pull exercise is pretty self-explanatory. Here, special notice should be taken to ensure that the elbows and wrists are secure. Larger back muscles will also help you complete this exercise properly. In addition to free weights, Resistance bands (http://SuperExerciseBand.com ) are also a great way to ensure that mothers choose exercises according to their fitness levels.
