Osteopenia, Dumbbells, and a Nervous Back
Elena, 70, is a retired teacher told she has osteopenia at the femoral neck (T-score -1.8) after a screening DEXA. She has no fractures, no back pain, and no contraindications to exercise, and her physician has cleared her for moderate-to-vigorous work. She walks 20 minutes three times a week and has never done resistance training. She has read that 'lifting builds bone' and wants a home program using the dumbbells and bench she already owns. Her 1RM is unknown; she can complete 8 bodyweight sit-to-stands from a standard chair. She is motivated but says she is afraid of 'throwing my back out.'
1. Design her resistance training program: frequency, intensity, sets, reps, exercises, and how you set the starting load without a 1RM test.

Structure - 2-3 nonconsecutive days per week, 8-10 exercises covering hips, spine, and major muscle groups, plus continued weight-bearing walking.
Intensity - for bone and muscle in an untrained older adult, target a load where the last 2-3 reps are hard but form holds (about RPE 13-15, roughly 65-75% 1RM), 1-2 sets initially building to 2-3 sets of 10-12 reps.
Exercise selection - hip hinge (dumbbell Romanian deadlift with a dowel against the back for feedback), sit-to-stand or box squat, step-ups to a low step, chest-supported row, wall or incline push-press, standing calf raise, and a light farmer carry. These load the hip and spine in the directions bone tolerates and rehearse movements she uses daily.
Setting the load without a 1RM - use a repetition-maximum approach: find a dumbbell she can lift 10-12 times with clean form and 2-3 reps still in reserve. That is functionally her training load. Avoid 1RM testing - it is unnecessary risk in a novice with low bone mass for no added programming benefit.
Address the fear directly - begin with bodyweight and dowel work, teach the hip hinge, and explain that controlled loading is what stimulates bone. Anxiety that is never addressed becomes dropout.
2. Which movements do you modify or exclude given her bone status, and what do you substitute?
Read the worked answer
The main hazards are loaded spinal flexion and rotation combined with breath-holding, because they concentrate compressive and shear load on vertebrae that may have reduced density.
Exclude or modify
- Crunches, sit-ups, and machine abdominal work that flexes the spine under load.
- Toe touches, standing forward folds, and seated forward-fold stretches performed ballistically.
- Bent-over rows or deadlifts performed with a rounded back.
- Russian twists and any seated rotation with a weight.
- Breath-holding (Valsalva) on any lift - cue exhale during the effort.
- Ballistic and explosive movements, and jumping, which she is not prepared for.
Substitute
- Chest-supported or single-arm supported rows instead of unsupported bent-over rows.
- Dead bug or a partial-range plank instead of crunches for trunk work.
- Hip hinge with a dowel or wall reference to keep a neutral spine.
- Static stretching held 15-30 seconds instead of ballistic stretching.
Impact is not forbidden for osteopenia without fracture - it is potentially useful - but introduce it gradually (marching in place, then low hops) only after strength and confidence improve, and only with physician awareness.
3. How do you progress her over 12 weeks, and what would prompt you to refer her back to her physician?
Read the worked answer
Weeks 1-3 - learn 8 movements with light or bodyweight load, 1-2 sets, focus on the hip hinge and breathing. Weeks 4-8 - add load by roughly 2-5% once she completes 12 clean reps with reserve, move to 2 sets, and add a low step-up. Weeks 9-12 - 3 sets on the largest movements, add a loaded carry and a modest impact component, and reassess with a 30-second chair stand and an estimated 10RM.
Refer back to her physician for new or sudden back pain (particularly if it is sharp, band-like, or accompanied by loss of height or increasing kyphosis), any fall, pain that persists beyond 24 hours after a session, new hip or groin pain, or unexplained fatigue. These can signal vertebral fracture or another process that exercise should not be pushed through.
Also close the loop on her screening DEXA - a screening result without a follow-up plan deserves a physician conversation, and your scope is to train her, not to interpret bone density. Document her baseline chair-stand score and her self-reported fear rating so progress is visible to her, not just to you.
