Train on three nonconsecutive days, such as Monday, Wednesday and Friday. Start each session with one warm-up round, then complete the selected main session in order. Each listed dose is per round; / side means do both sides.
Keep effort around 3–5 out of 10. You should be able to breathe throughout each exercise.
This is general fitness education, not individualized treatment. It complements other appropriate activity rather than replacing a complete fitness program.
Choose your week, then follow the session scheduled for your day. Repeating a week is always an option.
Use one round of each main session. Choose the easier versions freely. Learn a calm breathing rhythm and steady movement.
Three nonconsecutive days
1 main round per session
Keep movements small and comfortable. Warm-up dose stays the same all four weeks.
Sit upright in a supported chair and use the same easy breathing.
Avoid: Forceful exhales, breath-holding or trying to force a posture correction. Stop if lightheaded.
Sit in a chair and gently move the knee forward over the foot while keeping the heel down.
Avoid: Forcing through front-of-ankle pinching, bouncing, or lifting the heel to reach farther.
Stand closer to the counter and make the movement smaller.
Avoid: Rounding deeply, throwing the head back, or forcing a hamstring stretch.
Rest 20-40 seconds between exercises and 60-90 seconds between rounds. Take longer if needed. For repeated holds, relax about 5 seconds between holds. Do both sides wherever “/ side” is listed.
Keep head and shoulders down; practice a gentle abdominal brace while breathing for the same short holds.
Avoid: Neck strain, pulling the head forward, a sit-up motion, or bearing down.
Dose shown is per round. Complete 1 round of the main session when ready.
Standing side-wall press: place a bent forearm on the wall, feet close to the wall, and lean very slightly into it while keeping the body straight.
Avoid: Shoulder pain, twisting, sagging, or holding your breath. A floor side plank is optional, not a requirement.
Dose shown is per round. Complete 1 round of the main session when ready.
Move one limb at a time, or stand with hands on a counter and slide one foot back without arching.
Avoid: Reaching so high that the back arches, twisting the hips, or pressing through wrist pain.
Dose shown is per round. Complete 1 round of the main session when ready.
Use a smaller lift. If floor access is difficult, use the supported hip hinge for 8 slow repetitions instead.
Avoid: Pushing through back pain or hamstring cramping. Reset foot position or use the easier option.
Dose shown is per round. Complete 1 round of the main session when ready.
Sit in a chair and raise both heels while the balls of the feet stay on the floor.
Avoid: Bouncing, rolling the ankles outward or pushing through Achilles or foot pain.
Dose shown is per round. Complete 1 round of the main session when ready.
Leave the other toes lightly on the floor as a kickstand. Keep firm hand support.
Avoid: Closing the eyes, standing on unstable cushions or letting go of support to chase a longer time.
Dose shown is per round. Complete 1 round of the main session when ready.
After a main session, optionally add one set of the supported split-stance hip stretch and the seated cushion squeeze. These are not required and do not replace the main exercises.
Use a shorter stance or skip it if there is pinching or difficulty balancing.
Avoid: Deep lunging, forcing the pelvis forward, or stretching through joint pain.
Use less pressure or omit if it produces groin discomfort.
Avoid: A hard maximal squeeze or pain. Use this beginner option before considering demanding Copenhagen variations with a coach.
Optional easy-day practice: one warm-up round, then one 10-second supported balance hold per side. About 5 minutes. Keep it easy or take a full rest day; do not repeat the full strength session daily.

No perfect streak required. If recovery or symptoms change, reduce the dose or repeat the prior week.
At the start and after week four, note your comfortable ankle-rock range, hand support needed for a 10-second balance hold, and which core options you can perform with steady breathing. Use the same setup each time. These are personal observations, not diagnostic tests or pass/fail standards.
Continue at a comfortable level or get individual guidance. You do not have to make an exercise harder simply because four weeks have passed.
