Definition

Progressing from light to heavy loads set by set, adding weight until only a few repetitions are possible.

Detail

As the name implies, the light-to-heavy system entails programming from light to heavy resistance. It consists of performing a set of repetitions with a relatively light resistance. Additional weights are then added to the bar or weight stack and another set of repetitions is performed. This is continued until only several repetitions can be performed (Hatfield & Krotee, 1978).

The research to date, though sparse, favors a heavy-to-light system over a light-to-heavy system in producing strength gains (McMorris & Elkins, 1954; Leighton et al., 1967).

Key facts

  • Sets ascend from light to heavy resistance.
  • Weight is added each set until only several reps can be completed.
  • Research (though sparse) favors the reverse (heavy-to-light) for strength gains.

Principle of Progressive Overload
To keep improving, gradually make training harder than your body is used to: more weight, more reps or more sets. You don't need to add weight every week or go to failure. Small, steady increases you can recover from are what work.
Intensity
The amount of weight (resistance) lifted — also shaped by speed, reps, sets, rest interval, and workout duration.
Repetition Maximum (RM)
The maximum weight that can be lifted for a specific number of reps to exhaustion — e.g. a 6 RM is the load you can lift for exactly six reps.
Heavy-to-Light System (Descending)
After a brief warm-up, the heaviest set is done first and resistance is lowered each succeeding set; research favors it over light-to-heavy for strength.
Pyramid (Triangle) SystemClosely related
A favorite of power-lifters and bodybuilders combining ascending then descending loading — reps fall as load rises, then reverse.
