Rate of Perceived Exertion (RPE) and Reps in Reserve (RIR) are valuable tools for optimizing training programs. RPE is a subjective measure of how hard a set feels, while RIR estimates the remaining repetitions possible before muscular failure. While often used for load prescription, RPE offers greater versatility. A coach might prescribe 3 sets of 10 bicep curls at an RPE of 8, allowing the lifter to adjust the weight based on their daily readiness. This autoregulation facilitates heavier lifting on good days and lighter lifting on recovery days, leading to improved strength gains compared to fixed programs.
RPE also helps manage training volume. One method involves fixing the sets and weight (e.g., 4 sets of squats at 70% 1RM) and continuing each set until reaching an RPE of 6-8. Alternatively, the lifter can choose the exercise, weight, and reps, performing sets until the target RPE is reached (e.g., sets of squats at a specific weight for 10 reps until an RPE of 8 is attained). A volume cap, such as 5-6 sets, can prevent excessive training. Tracking the last set RPE each week provides valuable feedback on strength progress, indicating when to increase the weight.
The debate continues regarding the effectiveness of compound versus isolation exercises for muscle hypertrophy. A study comparing dumbbell rows to bicep curls demonstrated that isolation exercises yielded superior biceps growth. This suggests that isolating the biceps is crucial for maximizing hypertrophy, particularly beyond the beginner stage. However, other factors, such as range of motion and the likelihood of a muscle being the limiting factor in an exercise, influence the hypertrophic response. For example, lat pulldowns might stimulate more biceps growth than dumbbell rows, potentially due to biceps fatigue being a limiting factor.

Consideration should be given to bi-articular muscles, which cross two joints. For optimal development, these muscles benefit from exercises targeting both functions. For instance, the long head of the triceps, involved in elbow and shoulder extension, responds well to skullcrushers performed with the arms slightly overhead, incorporating shoulder extension. Similarly, the hamstrings, crossing the hip and knee joints, require both leg curls (knee flexion) and hip hinge movements like Romanian deadlifts (hip extension).
Processed foods pose a challenge for maintaining a healthy diet and body composition. A controlled study revealed that individuals consumed 500 more calories per day on a processed food diet compared to an unprocessed diet matched for macronutrients and fiber. This increased intake likely stems from the faster consumption, reduced appetite suppression, and lower protein content of processed foods.

While macronutrient tracking can be effective for weight management, it’s often unsustainable long-term. Unprocessed diets, rich in fruits, vegetables, lean proteins, and whole foods, promote satiety, reduce hunger, and naturally lower calorie intake. This makes them ideal for effortless fat loss, especially for those not tracking macros.
Alcohol consumption impacts training, recovery, and overall physique goals. While moderate intake may not significantly affect recovery measures like isokinetic strength or creatine kinase levels, heavy drinking can negatively impact hydration, sleep, and subsequent training performance. Moreover, alcohol blunts muscle protein synthesis, and this effect is more pronounced in men than in women, possibly due to the protective effects of estrogen.
Consistent high alcohol intake can hinder progress towards physique and strength goals, negatively impacting sleep quality and reducing testosterone levels over time. Moderate alcohol consumption, however, fits within a balanced lifestyle. Key is to be mindful of alcohol’s potential to lower inhibitions and lead to overconsumption, which can negate dietary efforts.
Alcohol and its effect on muscle growth
The concept of “muscle confusion,” advocating constant variation in training, lacks scientific support. A study comparing constant versus varied training programs over eight weeks found identical leg growth in both groups. Consistent training with progressive overload remains crucial for muscle growth, regardless of exercise variation. However, varying exercises over longer periods (e.g., between training blocks) can introduce novel stimuli and prevent stagnation, promoting continued adaptation.
Sodium bicarbonate (baking soda) supplementation may offer some performance benefits, especially in high-volume training with short rest intervals. By buffering acid buildup in muscles, baking soda can delay fatigue and potentially enhance training volume. However, the recommended dosage (0.3mg/kg bodyweight) can cause gastrointestinal discomfort. It’s advisable to test tolerance on a non-training day and split the dose into three portions.
Intermittent fasting (IF) can be a viable dietary approach for lifters, provided the eating window isn’t excessively restricted and protein intake remains sufficient. An 8-hour eating window, with training occurring in the fed state, allows for adequate nutrient intake and supports training adaptations. While not necessarily superior to more evenly distributed protein intake for maximizing muscle protein synthesis, IF can improve dietary adherence and hunger management.
Sodium Bicarbonate and Intermittent Fasting
Training to failure on every set can hinder muscle growth. Managing fatigue through strategies like RPE helps optimize training intensity and promotes long-term progress. By leaving some reps in reserve, lifters can minimize excessive fatigue and maximize hypertrophy.
