  We revisit the muon magnetic moment (g-2) in the context of Composite Higgs
models and Technicolor, and provide general analytical expressions for
computing the muon magnetic moment stemming from new fields such as, neutral
gauge bosons, charged gauge bosons, neutral scalar, charged scalars, and exotic
charged leptons type of particles. Under general assumptions we assess which
particle content could address the $g-2_{\mu}$ excess. Moreover, we take a
conservative approach and derive stringent limits on the particle masses in
case the anomaly is otherwise resolved and comment on electroweak and collider
bounds. Lastly, for concreteness we apply our results to a particular
Technicolor model.
