A
AMRAP - As Many Reps/Rounds As Possible
AMRAP is a high-intensity training format: do as many reps or rounds as possible in a fixed time. CrossFit favorite.
ATP (Adenosine Triphosphate)
ATP is the universal energy currency of the body. Every muscle contraction, every cellular function depends on it.
Aerobic System
The aerobic system produces energy with oxygen, fueling long-duration efforts. It's the foundation of endurance and recovery.
Anaerobic System
The anaerobic system produces energy without oxygen — for explosive, intense efforts. Limited but powerful, it fuels strength and sprints.
B
Block periodization
Block periodization concentrates training into focused blocks (accumulation, intensification, realization) with clear priorities.
Blood flow restriction (BFR)
BFR training uses cuffs to partially restrict blood flow so lighter loads can still stimulate hypertrophy — with safety constraints.
C
Calisthenics
Calisthenics builds strength and skill primarily with bodyweight patterns (push-ups, pull-ups, dips, levers) and progressive variations.
Circuit training
Circuit training chains several exercises with little rest. Ideal for burning calories and improving cardiovascular fitness while keeping muscle.
Cluster sets
Cluster sets break a set into mini-bouts with short intra-set rests to keep bar speed and load high — useful for strength and power.
