## TL;DR

Strength training builds strength through progressive overload: gradually increasing resistance while maintaining trained movement patterns. Compound exercises are multi-joint movements such as the squat, deadlift, bench press, overhead press, and pull-up.

## Core Explanation

Rep ranges are commonly programmed differently for strength, hypertrophy, and endurance goals. Progressive overload can come from adding weight, reps, sets, or reducing rest. DOMS is common after new or unaccustomed exercise and ACSM material says soreness can be greatest between 24 and 72 hours after exercise.
