Bolt – Workout & Strength Log

Daily Bodybuilding Gym Tracker

View

Bolt is a workout tracker you can actually use in the gym. Try this interactive journal to track your fitness journey and plan effective warm-ups and working sets.

What we love: Bolt’s extensive library of curated exercises help you build consistent, informed workouts. Try regimens designed by certified personal trainers and world-class Olympic athletes, or make one of your own.

Keep track of past reps and weight volume so you can easily adjust for gains.

Quick tip: Bolt knows that adequate rest is just as important as being active. Use the app’s rest timer to dial in the perfect amount of recovery time between sets.

Meet the creator: Seattle-based iOS engineer Bryan Dubno initially built Bolt as a personal tool to track his workouts and rest times. Encouraged by friends who were using complicated spreadsheets to track theirs, Dubno launched the app in 2018.
