Final answer:
Pregnant women often suffer from back strain due to increased weight and hormonal changes. Pelvic tilting and leg lifting can help alleviate backaches.
Step-by-step explanation:
Pregnant women often suffer from back strain late in their pregnancy due to several factors.
One reason is the increased weight and pressure on the spine and back muscles as the baby grows. This can cause the muscles to become tired and strained, leading to backaches.
Another reason is the hormonal changes that occur during pregnancy. These hormones cause the ligaments in the body to relax, including those in the spine. This can lead to instability and further strain on the back.
When a pregnant woman complains of backaches, exercises such as pelvic tilting and leg lifting can be beneficial. Pelvic tilting helps to strengthen the muscles in the lower back and pelvis, while leg lifting can help improve overall strength and stability.
