Measuring progress in strength training effectively involves a combination of methods. Tracking the amount of weight lifted, the number of repetitions, and the frequency of workouts provides quantifiable data on improvements. Regularly assessing muscle endurance, strength, and overall performance during workouts helps gauge progress over time. Additionally, monitoring physical changes, such as muscle definition and body measurements, can offer insight into progress. Maintaining a workout journal is a useful practice for staying accountable and adjusting training programs to continue making gains in strength and overall fitness.
