If you follow Hannah Bronfman on Instagram (or have seen her in the flesh), you're well aware that the DJ and founder of fitness and lifestyle site HBFit is in pretty sick shape. At all hours of the day, you can expect her feed to be rife with how-to videos and insanely agile poses against picturesque backdrops, exhibited by both Bronfman and her equally toned fiancé, Brendan Fallis. Since we know the key to executing a good workout is the music, we reached out to her to find out what songs get her in the zone. From "Roses" by The Chainsmokers ("great for cardio") to "100" by The Game feat. Drake ("a solid choice for reps with free weights"), these nine jams will have you sweating in no time at all.
