What it buys you
A sandbag shifts and settles like a person does. It is the closest loaded rehearsal for a supported lift.
Capacity trained
Strength. Posterior chain and trunk endurance under load. Holds position without fatigue or compensation.
Energy
Modelled kilocalories
| Reference body | 10 min | 20 min | 30 min | 45 min |
|---|---|---|---|---|
| Male reference · 82 kg | 103 kcal | 207 kcal | 310 kcal | 465 kcal |
| Female reference · 68 kg | 86 kcal | 171 kcal | 257 kcal | 386 kcal |
Energy figures are modelled from standard activity MET values (Ainsworth Compendium, 2011) and the ACSM equation, not measured on you. They scale linearly with your own body mass, so a body 10% heavier burns about 10% more at the same intensity.
kcal = METs × 3.5 × bodyweight(kg) ÷ 200 × minutes (ACSM)
Load is effort, not pain. If a movement hurts rather than works, stop and see a clinician. Lifting another person is strength training with a person-shaped load — build the pattern unloaded first.

Honest framing
Training makes a posture available and sustainable. It is capability work, not a treatment for anything, and no single session changes a number. Consistency over eight weeks does.
