Felipe Isidro, Physical Education teacher: 70From the age of 70, legs are much more important to your health than you think

Felipe Isidro, professor of physical education, emphasized during a conversation with Uri Sabat that after the age of 70, leg strength becomes critically important for health. He explained that while the body retains slow-twitch muscle fibers longer, fast-twitch fibers, essential for power and explosive movement, are rapidly lost. This leads to difficulties such as extreme fatigue or pain when climbing stairs, which he described as a common yet overlooked issue among older adults. The loss of fast-twitch fibers directly impacts daily mobility, making tasks like ascending a step more challenging than walking on flat ground. A single step requires a leg to bear up to four times the body weight while keeping the knee at a 90-degree angle. Isidro stressed that training is not optional but essential for survival, arguing that leg strength serves as a better indicator of overall health than traditional clinical tests measuring glucose or cholesterol levels. He claimed that stronger legs contribute to longevity, reduce fall risks, and prevent multiple health complications. Isidro debunked myths about aging, stating that anyone capable of breathing can train. He noted that functional decline is not an inevitable fate but a consequence of inadequate stimulation. Physical exercise, therefore, becomes a vital tool for maintaining independence. To counteract weakness, he proposed a comprehensive program combining technique, muscle strengthening, and minor home modifications. The routine includes exercises such as standing up from a firm chair using arm support in sets of ten repetitions, mimicking the effort of climbing one step. He recommended calf raises against a wall to strengthen the calves and controlled steps onto a single stair. Proper posture when ascending stairs, such as leaning forward to shift weight toward the glutes, helps reduce joint stress. For individuals suffering from arthritis, pre-strengthening and installing handrails offer greater safety. Traditional daily walks of 10,000 steps are insufficient without incorporating varied rhythms or elevation changes. Isidro emphasized that resistance training using weights or bodyweight is crucial for stabilizing the body. He argued that the lack of specific exercises, rather than time alone, explains the loss of essential motor skills in domestic settings. Separately, Chris Bumstead, known as CBUM, shared his approach to bench pressing. He preferred lifting 165 kilograms in multiple repetitions over chasing a single maximum lift. His method prioritized sustained performance over raw strength, aligning with his focus on aesthetic development in the Classic Physique category of Mr. Olympia. Bumstead won six consecutive titles from 2019 to 2024 under this framework. He avoided exercises and loads that could compromise shoulder health, especially after experiencing joint injuries. His training focused on safety, technical control, and muscular stimulation rather than pursuing absolute records. Bumstead acknowledged the demands of competitive bodybuilding, noting that professional physique training involves factors beyond gym workouts, including nutrition and supplementation. In a candid moment, Bumstead linked competitive success to the use of steroids, acknowledging their role in achieving the desired physique. He warned that high-performance in bodybuilding is not suitable for everyone and comes with significant health considerations.
