  We propose a novel strategy to constrain the bottom and charm Yukawa
couplings by exploiting LHC measurements of transverse momentum distributions
in Higgs production. Our method does not rely on the reconstruction of
exclusive final states or heavy-flavour tagging. Compared to other proposals it
leads to an enhanced sensitivity to the Yukawa couplings due to distortions of
the differential Higgs spectra from emissions which either probe quark loops or
are associated to quark-initiated production. We derive constraints using data
from LHC Run I, and we explore the prospects of our method at future LHC runs.
Finally, we comment on the possibility of bounding the strange Yukawa coupling.
