Common Mistakes

  • Focus on the mind-muscle connection — feel the target muscle working through each rep.
  • Use a controlled tempo of 2 seconds up, 2 seconds down to eliminate momentum.
  • If reps become too easy, slow the tempo or add a pause at the hardest point rather than rushing through more reps.
  • Squeeze at peak contraction for a full second — this is where most of the growth stimulus occurs.
