Is a 45 Minute Workout Enough? A Coach's Honest Answer

Somewhere along the way, a lot of us picked up the idea that a “proper” workout takes 90 minutes, a long drive to a big gym and a protein shake in the changing room. Then kids arrived, and suddenly that felt impossible, so we did nothing. If you are wondering is a 45 minute workout enough, my answer, after more than 10 years of coaching busy parents in Archway, is a confident yes for most people. Here is why, what to put in those 45 minutes, and how often you need to do it.

What the NHS actually asks of you

The NHS physical activity guidelines for adults recommend:

• At least 150 minutes of moderate intensity activity a week, or 75 minutes of vigorous activity, or a mix of both.
• Strengthening activities that work all the major muscle groups on at least 2 days a week.
• Spreading activity across the week and reducing time spent sitting.

Now do the maths. Two 45-minute sessions that include strength work and some harder intervals give you 90 minutes and tick the 2 strength days. Add 20 minutes of brisk walking on three or four other days, for example the school run, and you are comfortably at the target. Nowhere does it say each session has to be long.

Is a 45 minute workout enough to make progress?

For most busy parents, yes. What drives progress is not the length of one session but these three things:

1. Consistency. Two 45-minute sessions every week for six months beat one 2-hour session whenever you can manage it.
2. Effort. A focused 45 minutes with clear work and short rests is worth more than 90 minutes of wandering between machines and scrolling your phone.
3. Gradual overload. Doing a little more over time: a heavier weight, an extra round, a harder version.

Where 45 minutes may not be enough is if you are training for something specific, such as a marathon, or chasing advanced strength goals. For general fitness, strength and energy, it is plenty.

How I use 45 minutes in a bootcamp class

Here is how an SYP Bootcamp session breaks down. There is no wasted time, and every exercise has an easier and harder option.

Time	Block	Example
0 to 7 min	Warm-up	Marching, hip circles, arm swings, light squats and lunges
7 to 27 min	Strength	3 rounds: goblet squat x 10, row x 10 each side, push-up x 8 to 12, glute bridge x 12
27 to 39 min	Conditioning	4 rounds of 40 seconds work and 20 seconds rest: step-ups, slam balls, mountain climbers
39 to 45 min	Cool-down	Stretches for hips, chest and back, slow breathing

Because I cap groups at 10 people, there is no queueing for kit or waiting for instructions. If you want more session ideas, have a look at my 45-minute bootcamp workout ideas.

How to make your own 45 minutes count

If you train at home or in a gym, use these rules:

• Plan before you start. Write down your exercises, sets and reps. Deciding as you go wastes time.
• Use supersets. Pair two exercises that use different muscles, such as squats and push-ups. Do one, then the other, then rest. You get twice the work in the same time.
• Keep rests honest. 60 to 90 seconds for strength, 20 to 30 seconds in intervals. Use a timer.
• Prioritise big movements. Squat, hinge, push, pull and carry give you the most for your time.
• Leave the phone in the bag until the cool-down.

What about even shorter sessions?

On weeks when 45 minutes is impossible, shorter still counts, because some activity is always better than none. Ten or fifteen minutes of squats, push-ups and a plank in the living room after bedtime is a perfectly good session. My 10-minute workout for busy parents is designed exactly for those weeks.

How many 45-minute sessions a week?

• 1 a week: a great start, and better than nothing. Add daily walking.
• 2 a week: the sweet spot for most parents. Covers your strength days.
• 3 a week: brilliant if you can manage it and recover well.

I go into more detail in is two classes a week enough. If your energy is low, a lively but manageable class like SYP Recharge for energy and focus is a good place to start.

If you have a health condition, have been inactive for a long time, or have recently had a baby, check with your GP before starting a new exercise routine.

FAQs

Is 45 minutes of exercise a day too much?

For most healthy adults, no, especially if some days are gentle, like walking. Build up gradually and take rest days when you need them.

Is 45 minutes of strength training enough?

Yes. For general strength, 45 minutes two or three times a week, working the major muscle groups, is enough for most people.

Is 45 minutes of cardio enough?

Yes. Four 45-minute sessions of moderate cardio, such as brisk walking or cycling, would meet the NHS target of 150 minutes a week on their own.

Should I warm up within the 45 minutes?

Yes. A good warm-up is part of the session, not extra. The NHS explains how to warm up before exercising.
