| Variety is best. Break your training year into several periods and spend one period with high-intensity/low-weight like 4-8 reps to failure, another period with medium-intensity/medium-weight (8-12 to failure), annother on higher reps (12-20 reps to failure), another period on strength-specific (4-8 reps, stopping well short of failure), possibly another on power training (olympic lifts, plyometrics), etc. |
