Answer:
Flag football.
Step-by-step explanation:
In order to get strong muscles to be able to lift heavy objects, Yahaira needs to develop and strengthen her thighs, buttocks, and abdominal muscles. These areas will help her get the core strength to be able to do the heavy lifting.
Despite certain beliefs that carrying heavy loads involves the muscles of the shoulders, biceps, and abdomen, the lifting muscles are what makes it possible and easy to do the heavy lifting. And for that, flag football is one activity that will help develop not only the shoulders, biceps, and triceps but will also help sculpt the calves, abdomen, and leg muscles.
Thus, Yahaira should get involved in flag football to improve her power to lift heavy objects.
