Light-to-Heavy System (Ascending)
0% read · 1 min left
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.
Connections
- heavy-to-light — the reversal of this system, favored by research for strength.
- pyramid — combines ascending and descending loading.
- progressive-overload — load increases progressively within the session.
