What type of training should be avoided for clients with a history of joint issues?

High-impact training should be avoided for clients with a history of joint issues because it involves activities that put significant stress on the joints, such as jumping, running, or other exercises that include rapid changes in direction and high levels of force. These types of movements can exacerbate existing joint pain or lead to further injury. The impact from high-intensity activities can increase joint strain and may aggravate conditions like arthritis or tendonitis, making it essential to consider alternatives that are lower in impact and safer for the joints.

In contrast, low-intensity exercise, strength training, and flexibility training can often be beneficial for clients with joint issues when performed correctly. Low-intensity exercises, for example, provide cardiovascular benefits without excessive strain. Strength training can help improve the stability and support of the muscles around the joints, potentially reducing the risk of injury. Flexibility training enhances the range of motion and can help alleviate stiffness without adding undue stress on the joints. Thus, these training types can be more suitable for clients with a history of joint issues, provided they are tailored to their specific needs and limitations.
