Contrary to gym lore, longer rest periods are more effective for muscle growth. Taking 60-120 seconds between sets allows for better recovery, enabling higher-quality repetitions and greater total volume (weight x reps x sets), which is the primary driver of hypertrophy.

Changing exercises too frequently prevents progressive overload, a key driver of adaptation. It takes about three weeks to master an exercise's mechanics and appropriate loading. Sticking with the same movements for a longer period is more effective than constant variation.

On days with limited time, adapt your workout to your primary goal. For strength, maintain high loads and cut sets/reps (volume). For muscle growth (hypertrophy), maintain volume by using lighter weight and shorter rest periods to ensure sufficient stimulus.

Rigidly sticking to a 7-day training schedule can compromise recovery, as your muscles don't operate on a calendar. Adopting a flexible 9- or 11-day cycle allows each muscle group to fully recover, leading to better long-term gains and fewer injuries.

For strength and power development, structure workouts around compound movements like pushing, pulling, hinging, and rotating. This approach builds functional strength that translates to real-world activities, unlike isolating individual muscles, which is a concept better suited for bodybuilding.

Instead of pushing for linear gains indefinitely, Yates recommends periodizing training. Go all-out for five to six weeks, then intentionally back off for two weeks with lighter, submaximal workouts. This "sawtooth" pattern allows for full recovery and prevents plateaus.

Since strength equals mass times acceleration, intentionally slowing down reps is counterproductive for strength goals. For hypertrophy, however, slowing the tempo (increasing time under tension) is a useful tool to increase stimulus, especially when using lighter weights, but is not a core requirement.

Contrary to gym lore, scientific literature shows that any repetition range between 5 and 30 reps per set produces similar muscle growth, provided the set is taken to muscular failure. This allows for greater variety and flexibility in program design.

The specific exercise you choose (e.g., bench press) does not determine the outcome. Rather, the adaptation (strength vs. endurance) is dictated by variables like intensity, sets, reps, and rest periods. The application of the exercise is the primary driver of results.
