What to Expect Your First Week
You WILL be sore. That's normal. It's called DOMS (Delayed Onset Muscle Soreness) and it means it's working.
The soreness starts to ease. Your body is adapting.
You'll start to feel the routine. Energy levels improve. Keep going.
The first week is the hardest. After that, it gets easier.
Equipment Guide
For the 50+ and Low-Impact programs: Zero equipment is required for many workouts.
Exercise Glossary
These terms come up constantly in every program. Bookmark this page.
HIIT
High-Intensity Interval Training. Short bursts of hard effort followed by rest. Burns a lot of calories in a short time.
Sets
A group of consecutive repetitions. "3 sets of 10" means you do 10 reps, rest, do 10 more, rest, do 10 more.
Reps (Repetitions)
One complete movement. One squat = one rep.
Rest
The time you wait between sets. Follow the rest times — they're there for a reason.
RPE (Rate of Perceived Exertion)
A 1–10 scale for how hard you're working. RPE 7 means working hard but you could still speak a few words.
Superset
Two exercises done back-to-back with no rest between them.
Compound Movement
An exercise that works multiple muscle groups at once (squats, deadlifts, push-ups).
Isolation Movement
An exercise targeting one specific muscle (bicep curl, lateral raise).
Progressive Overload
Gradually increasing weight, reps, or intensity over time. This is how you keep making progress.
Tempo
The speed of each rep. "3-1-3" means 3 seconds down, 1 second pause, 3 seconds up.
Warm-Up
Light movement to raise your body temperature and prep your joints before the main workout.
Cool-Down
Gentle stretching after the workout to reduce soreness and improve flexibility.
