Weight jumps

How much to add when every set hits the top of its rep range. Match these to the next dumbbell or pin at your gym.

How suggestions work

• Every set hits the top of its rep range: move up. The new weight is filled in for you.
• Otherwise: stay at that weight and beat last time by a rep or two.
• No progress for 3 sessions in a row: try a lighter week, same weight with half the sets.
• Swapped exercises keep their own history, so the numbers stay comparable.
