Answer:
b weight training and pilates
Step-by-step explanation:
Weight training is a kind of strength training that uses different types of weights to create resistance. As an individual tries to work out using more weight, their muscles grow in size and become stronger. Pilates is a work out consisting of controlled movements which targets improving breathing, alignment and building a strong core. The core consists of abdomen muscles, hips and lower back and pilates increases the muscle mass in these areas. Thus if Caryn wants to improve her fat to lean muscle ratio and muscle mass, she should do weight training and pilates. Yoga and gymnastics work more to improve body flexibility. Cycling, aerobics, jogging and swimming come under cardio exercises which help to lose weight and improve heart functioning.
