Dumbbell-Only Upper / Lower (4×/Week), Double Progression

How it runs

Every muscle group is trained twice a week and receives between ten and nineteen hard sets.

What you actually train

4 sessions, in order. Every movement links to how to do it.

  1. Upper A

    7 movements

  2. Lower A

    6 movements

  3. Upper B

    7 movements

  4. Lower B

    6 movements

Why it works

  • Fourteen sets each for back and hamstrings, both of which a dumbbell can genuinely load once the programme knows how to ask.
  • Four days rather than three because ten muscles at ten sets each does not fit into three sessions anybody finishes at home.
  • Double progression matters more here than with a barbell, because dumbbells jump in two-kilo steps — you earn the next pair rather than guessing at it.
  • When the dumbbells run out there are three levers in order: slow the lowering, move to a harder version of the movement, and only then add a set.
  • Movements are paired so a push and a pull share their rest, which is what keeps a home session to about fifty-four minutes.

There is no vertical pull here, because a dumbbell cannot make one. If you can fit a doorway pull-up bar, a few sets of slow lowering from the bar are the one addition that fills that hole.

What to expect

Expect the single-leg work to take longer than the set count suggests, because every one of those sets is really two.

Before you start

Before you start, please read this part. Lifting is among the safest and most useful things most people can do, and there is a short list of exceptions worth checking yourself against first.

If you have a heart or lung condition, chest pain or pressure at rest or on effort, dizziness or blackouts, blood pressure or diabetes that is not currently controlled, a hernia, low bone density or osteoporosis, a joint or back problem that is flaring, or you are pregnant or within a year of giving birth, speak to your GP or a physiotherapist before starting and follow their instruction over anything written here.

Stop the set and get advice for chest pain or tightness, breathlessness out of proportion to the effort, dizziness, or a sudden sharp pain in a joint or the back.

Stop it as well for pain, numbness, pins and needles or weakness that travels down an arm or a leg, and get that seen before you load the pattern again.

Training alone at home, keep a rep in reserve on the pressing movements — there is nobody to lift a dumbbell off your chest. Nothing here is medical advice.
