HIIT training is best when cutting as it reduces the amount of muscle that is used as fuel (due to the short time doing it).
The good thing about running for only 20-30mins is that you have not stressed out the leg muscles too much, and so the recovery time is shorter.
Im cutting at the mo.
Im running for 20mins (plus 5mins warm up+5mins cool down)
then weight training 1day on, 1day off.
doing an upper body and core 3day split
chest, lats/traps, shoulders,/ arms, core
not worrying about legs for now as im running everyday, and loosing the fat is most important.
