Welcome to JeanFit

Train smart. Lose steady. Stay safe.

JeanFit adapts your program around energy, autoimmune flare risk, dizziness, blackout risk from level changes, nutrition, and long-term maintenance.

Safety: JeanFit is not medical care. Stop for faintness, chest pain, severe shortness of breath, confusion, new neurologic symptoms, or flare symptoms that feel unsafe. Seek urgent care for severe or persistent symptoms.

for keeping it off

Intensity Dial

RPE guided
Stop the session if you feel faint, dizzy, chest pain, unusual shortness of breath, confusion, blurred vision, or symptoms that feel like a flare. Sit or lie down, hydrate if appropriate, and seek medical care when symptoms are severe or do not resolve.

Rest Timer

Longer rests are productive when recovery is the limiter. Strength work does not need to feel frantic.

Maintenance Mode

after the cut

Weight maintenance usually needs consistent monitoring, adequate protein, strength training, and enough regular activity to match your new body size and appetite. JeanFit treats maintenance as a skill, not an afterthought.

Relapse Plan

normal, fixable
Green zone: within 0-3 lb of maintenance range. Keep routine, no extra restriction.
Yellow zone: 3-5 lb above range for two weeks. Add food logging for 7 days and one walk block.
Red zone: symptoms, binges, rapid regain, or blackout risk. Shift to recovery basics and discuss the pattern with a clinician or registered dietitian.

Evidence Notes
