Final answer:
Decrease the weight used when hitting failure on a tib raise to maintain form and avoid injury, rather than increasing repetitions or immediately continuing. Allow adequate rest and consider overall workout fatigue when managing recovery.
Step-by-step explanation:
When you hit failure on a tibial raise, which means you cannot complete another repetition due to muscle fatigue, the best course of action is usually to decrease the weight used. This adjustment allows you to perform the exercise with proper form and reduces the risk of injury. Options such as taking a short break and continuing or allowing for more rest days in between sessions can also be considered based on your overall workout schedule and fatigue level. It is not recommended to increase the number of repetitions immediately after hitting failure because this could lead to overtraining and does not allow the muscles adequate time to recover. In fact, consistently training to failure can be counterproductive if recovery is not optimized. Instead, focus on gradual progression and listen to your body’s cues for rest and recovery.
