About 1RM Formulas
Epley Formula: Most accurate for lower rep ranges (1-6 reps). Commonly used in strength training.
Brzycki Formula: More conservative estimates. Better for higher rep ranges (6-12 reps).
Lander Formula: Middle ground between Epley and Brzycki. Good all-around accuracy.
Note: These are estimates. Your actual 1RM may vary based on factors like fatigue, technique, and training experience. Always use a spotter when testing maxes.
Form Tips
- ✓Control each dumbbell independently — no bouncing off the chest
- ✓Keep wrists stacked over elbows throughout the rep
- ✓Use full range of motion, lower deeper than a barbell
- ✓Keep elbows at roughly 45 degrees from the torso
Common Mistakes
- ✗Pressing dumbbells inward at the top (unstable)
- ✗Flaring elbows to 90 degrees (shoulder impingement)
- ✗Using momentum or kicking legs to get into position
- ✗Not controlling the eccentric phase
