Any breastfeeding moms that work full time?

Hi! I'm a first time mom with a 3-months old baby. I plan to exclusively breastfeed at least 6 months, and would like to ease into exercise routine again. I was doing a bit of running and T-25 for almost a year before I got pregnant. Then, I completely stopped exercising after being 6 weeks pregnant, morning sickness was terrible. Any recommendations on diet and exercise routines, or just saying hi are pleasantly welcome!
