ReboundSA awarded as CANSA Smart Choice

15 October 2020 – CANSA announces that ReboundSA products, programmes and courses have been awarded the prestigious CANSA Smart Choice Seal of Approval, for use as part of a balanced lifestyle to lower your risk of cancer. Research shows that an increase in physical activity reduces the risk of developing several types of cancer including breast, bladder colorectal, endometrial (uterine), throat kidney and stomach.[1-14].  #LowerCancerRisk #CANSASmart Choice #ReboundSA

Lorinda Van Dyk, CANSA’s Seal of Recognition Coordinator, says, “Rebounding is a high cardio, low impact workout performed using a mini-trampoline (rebounder). Rebounding gained popularity as an exercise programme in the 1980’s when a study by NASA found that rebounding was more effective in building bone and muscle mass than running. The research, which looked at how different forms of exercise help astronauts regain loss of bone and muscle mass after time in space, found that rebounding increases oxygen uptake more than running does due to the increased g-force, and benefits the body on a cellular level at a greater rate than other methods of exercising.” [15]

Rebounding is not just a fun way to get moving, it also holds a wide range of overall health benefits. Rebounding has phenomenal immune supporting benefits on the body, particularly the lymph system. For this reason, rebounding is recommended as part of a cancer fighting strategy. Rebounding is further good for people living with cancer as a gentle low impact form of exercise. [16-17]

In his book Jumping for Health, Dr Morton Walker says that just two minutes of rebounding offers equivalent physiological benefits as six minutes of running, 10 minutes of swimming and 22 minutes of walking. Research has shown that it strengthens abdominal, leg, buttocks and back muscles while being gentle on joints. It stimulates the lymphatic system and subsequently assists with flushing out of bacteria, dead cells and other waste products in the body and builds bone strength as it supports bone formation, while decreasing bone resorption. [14]

The CANSA Seal was introduced to encourage South Africans to read product labels and to assist them in making informed choices – the aim being to promote smart, balanced lifestyles. By taking note of CANSA’s Smart Choice suggestions (including products such as ReboundSA), people are making a proactive effort in reducing their cancer risk. To qualify for the CANSA Seal, products must pass stringent tests aligned with South African National Standards (SANS), and / or similar International Standards.

ReboundSA’s easy to use equipment and fitness programmes are available for purchase online at and for rebounding classes, follow
