Tendons are critical for body movement and act as protective cables, absorbing load to prevent muscles from overextending. They need to be incredibly strong, but unlike muscles, require a different type of training. Dr. Keith Baar highlights that tendons respond differently to loads than muscles or the heart, explaining why many pains are tendon-related.
When muscles develop faster than tendons, it creates a strength imbalance, leading to pain and injury. This is evident in athletes using steroids, where rapid muscle growth can lead to tendon tears. Even without steroids, warning signs like joint clicking (especially with pain) indicate weak tendons.
Contrary to common belief, complete rest is detrimental to tendon healing. While pain might temporarily subside, the underlying problem isn't fixed. Rest can actually weaken healthy tendon parts and prevent damaged areas from rebuilding properly, leading to recurring pain, particularly as one ages.
Suddenly increasing activity volume or intensity by more than 30% can injure tendons because they adapt slower than muscles. The speaker shares a personal experience of developing tendinitis after increasing heavy lifting volume too quickly. It's crucial to gradually increase load and volume, adding at most one to two sets per week for a 30% jump.
Using momentum, such as bouncing weights during presses or squats, puts excessive stress on tendons. While Olympic weightlifters adapt to this, the average person's tendons are not accustomed to such forces. For general fitness, controlling the eccentric (lowering) phase of movements is gentler on tendons and can also facilitate muscle growth.
Isometrics, which involve contracting a muscle without movement (e.g., holding a position), are highly effective for healing and strengthening tendons. Dr. Keith Baar explains that sustained isometric holds (around 30 seconds) signal the entire tendon, including scarred areas, for collagen synthesis, leading to lasting strength and pain relief.
To perform isometrics, target the specific motion that causes pain. Examples include holding a position similar to a bench press for shoulder issues, or a curl for biceps pain. The video demonstrates specific isometric exercises for shoulders (chest press, overhead press, lateral raise), elbows (biceps curls, triceps push-downs/extensions), and knees (knee extension machine or wall sits).
To heal and rebuild tendons: choose one isometric exercise for the problematic joint; perform three sets twice daily (morning and evening). Temporary pain relief can occur in 1-2 weeks. For permanent results, continue exercises 3-4 times a week for 4-8 weeks. To maintain long-term tendon health, incorporate these exercises for 5-10 minutes after workouts or dedicate one day a week to them. The video also promotes their fitness app, which includes these exercises and joint-friendly alternatives.
