Reformer on the Mat! Feel all the good feels in those shoulders and legs, no big pieces of equipment necessary. 

Pro Tip: If you're not into strength workouts, play with increasing your weight and reps in some of these variations to amp up the challenge. 

Equipment: A slider/sock/face towel, something to elevate your heels such as a squish ball or rolled up yoga mat and a pair of light dumbbells.
