You can also directly add them to your Instagram Story! We think you should be proud of what you accomplish (especially if you broke your previous bench press max weight). Share that with style with our different cards: - Total volume lifted - Best set - Progress over time - Reps Only - Duration TIME-BASED EXERCISES You can also track your planks, stretching exercises, or yoga sessions. CALENDAR Another way to get motivated is to see how often you've worked out this week or month. We included a calendar that shows exactly that. You can quickly overview your past workouts and see exactly what exercises you performed on a specific day. THEMES Everyone has different tastes, we are totally fine if you don't like the default theme. That's why we included others. Prefer pink? Maybe black? We've got you covered!
