Everyone is as unique as a fingerprint but exercise definitely makes a difference for me personally during the evenings when the grip is tugging on me. Especially aerobic stuff. I've done regular bike rides, high rep/low weight workouts, and even doing 10 flights of outdoor stairs at my local elementary school.
By the time my heart rate returns to normal I feel completely different and surprisingly relaxed considering what time the clock says.
Before investing in a piece of equipment try out a simple cardio workout on youtube or just doing a bunch of stairs and see how you feel afterwards.
