Strong review

Strong is a deliberately simple gym log. Its App Store listing says the free version can save unlimited workouts but is limited to 3 custom routines, which works if you run a fixed program such as a 3-day full body plan. Strong says it is optimized for progressive barbell routines such as Starting Strength or StrongLifts 5x5. Logging covers cardio and strength exercises with a growing library of animated videos, sets tagged as warm-up, failure or drop sets, supersets and an automatic rest timer. Progress shows as personal records, calculated one-rep max, total weight lifted and graphs for volume and 1RM. Warm-up and plate calculators help at the bar, and the Apple Watch app logs workouts with or without the iPhone. You can export all data as CSV. Strong PRO removes the routine cap for $4.99 a month or $29.99 a year in the US. There is no program library, so beginners who need a plan should look at Boostcamp or Nike Training Club.
