Summer heat makes outdoor exercise difficult. Since overexertion raises the risk of heat illness, interest is growing in exercise that can be done safely indoors.

Seated moves that loosen the knees and lower back are especially something the elderly or those with weak joints can follow relatively safely, focusing on keeping muscles and joints supple without sudden motions.

Recently, AI-based exercise tools correct posture and help users follow along. An advantage is that with an 'AI coach' on the screen, one can keep exercising steadily even alone at home.

Still, those with pain or existing conditions should avoid overexertion and consult a professional to be safe. Exercise intensity and method should be adjusted to one's own physical condition.
