Key Insights

• Compound movements are the foundation of this session because they affect many muscles within each rep. Quads, hamstrings, glutes, shoulders, back and chest are all placed under load, while the biceps, triceps, core and abdominal muscles assist in performing the movements.
• The work-to-rest structure is 40 seconds of work followed by 20 seconds of rest for pretty much the entire session. This fixed interval keeps the pace consistent across the exercise list without requiring the participant to count reps.
• No repeat means each exercise is performed for only one set. The workout moves through a full sequence of different movements rather than cycling back through the same circuit multiple times.
• Quality of reps is prioritised over quantity. The stated approach is to control the dumbbells at all times and focus on as many quality reps as possible instead of as many reps as possible.
• Two dumbbell weights are used across the session. The instructor works with two 15 kg dumbbells for most exercises and drops to two 7.5 kg dumbbells towards the end for the shoulders and abs portion.
• Equipment is minimal: a mat and some dumbbells are all that is required. A barbell, kettlebells or bands can be substituted for some portions of the session if preferred.
• The abs and core finisher breaks the standard timing pattern. The alternating deadbug with two 7.5 kg dumbbells and the toe reach to leg lower with one 7.5 kg dumbbell each run 60 seconds, with no clear rest between the two final exercises.
• Several exercises are performed one side at a time with a switch, including the single arm bent over row, the static lunge and the rear step forward lean lunge. Each side gets its own timed block before moving on.

Questions & Answers

Q: How long is this dumbbell full body workout and how is it structured?

The session is 20 minutes long. The timer is set to 40 seconds of work followed by 20 seconds of rest for pretty much the entire session. Each exercise is performed for only one set, making it a no repeat workout rather than a repeated circuit. The exception is the abs and core specific portion at the end, which runs 60 seconds per exercise with no clear rest between the two final exercises.

Q: What equipment do you need for this 20 minute full body workout?

All you need is a mat and some dumbbells. The instructor uses two 15 kg dumbbells for most of the workout and drops to two 7.5 kg dumbbells towards the end for the shoulders and abs portion. Some exercises use a single dumbbell, such as the close stance squat and goblet squat with one 15 kg dumbbell. A barbell, kettlebells or bands can be used instead for some portions of the session if preferred.

Q: What muscles does a compound dumbbell full body workout target?

Quads, hamstrings, glutes, shoulders, back and chest are all placed under load in this session. The biceps and triceps, core and abdominal muscles are all required to assist in performing the movements. This happens because the workout is built from compound movements, which affect many muscles within each rep rather than isolating a single muscle group. The result is a session that works all the major muscle groups in the body to promote muscle building.

Q: What exercises are included in this no repeat dumbbell workout?

The sequence includes single arm bent over row on each side, front rack squat, chest press, static lunge on each side, renegade row, alternating rear lunges, pullover, RDL and push ups with two 15 kg dumbbells. It then moves to a close stance squat with one 15 kg dumbbell, shoulder press, rear step forward lean lunge on each side, lat sweeps with two 7.5 kg dumbbells, goblet squat with one 15 kg dumbbell and upright row. The finisher is an alternating deadbug and a toe reach to leg lower.

Q: Why focus on quality reps instead of as many reps as possible?

The instruction is to control the dumbbells at all times, even though this is a short duration full body workout. The stated focus is on as many quality reps as possible rather than as many reps as possible. With 40 second work intervals and compound movements loading multiple muscle groups at once, controlled execution is what keeps each set effective across the whole session.

Q: What is the abs and core portion at the end of this workout?

The abs and core specific portion at the end breaks from the 40/20 pattern and is simply 60 seconds in duration for each exercise, with no clear rest in between the two last exercises. It consists of an alternating deadbug using two 7.5 kg dumbbells followed by a toe reach to leg lower using one 7.5 kg dumbbell. The lighter dumbbells are introduced for the shoulders and abs portion towards the end of the session.

Q: Is a 20 minute full body workout enough to build muscle?

This is described as a great, shorter duration and efficient session to work all the major muscle groups in the body to promote muscle building. Because pretty much every exercise is a compound movement, each rep loads many muscles at once, so quads, hamstrings, glutes, shoulders, back and chest are all placed under load within the 20 minutes. It is presented as a session to return to regularly when you have 20 minutes and want a solid full body workout.

Q: When should you use this workout in your training week?

It is described as perfect for regularly returning to when you have 20 minutes and want a solid full body session. It suits times when you just want to get a great all over body workout done in a short window. Because it covers all the major muscle groups in one no repeat sequence, it works as a complete standalone session rather than a body part split day.
