  We analyse the epoch of reheating after an inflationary phase in the Randal
Sundrum(RS) Type-$\rm II$ braneworld, where we did not consider any particular
model of inflation, but rather reconstructed the inflationary potential solving
the flow equations using Monte Carlo (MC) approach. It is shown numerically
that a potential conceived through the MC reconstruction technique can be
represented by an effective potential as a function of the number of
e-foldings($N$). Then, the epoch of reheating is studied for this reconstructed
potential. The relation between the reheating temperature ($T_{\rm reh}$) and
the 5-dimensional Planck mass($M_5$) is established. Moreover, it is argued
that there is a stringent bound on the critical reheating temperature that also
translates to a tight bound on $M_5$ .
