Many people make the mistake of doing loads of crunches, but crunches only work the front wall of the stomach,” Yang says. “The core’s transverse and oblique muscles get ignored. This workout targets every muscle group that comprises the core—transverse, internal and external obliques and the rectus abdominus—leading to a strong center and svelte waistline.

Don’t think bad weather days are a free pass! Get yourself to the gym. Fitness expert, personal trainer, and running coach Daphnie Yang suggests cranking the incline up to a 2.0 to mimic outdoor conditions. “Treadmill running is slightly easier than running outdoors due to the track assisting your stride. Cranking up the incline makes it comparable to running flat outdoors
