January typically marks a time when many of us start to think about our fitness goals. With 12 fresh months to realise our aims, it’s not uncommon to head into the new year feeling super motivated. But too much exercise enthusiasm can have its downfalls, too, as it increases the risk of overtraining and overstimulating muscles by doing too much, too soon.
Check out our guide on how to motivate yourself to go to the gym
Your best bet? Find a good training programme to follow, as this will ensure you improve and make gains at the right pace. But what is the ‘right’ pace? When you operate at your threshold fitness level, one at which you can improve strength and cardiovascular fitness, while not feeling overly fatigued.
A programme can help with this. It provides a carefully constructed plan of what needs to be done to realise your fitness goals, including how many reps and sets to achieve each week. This will help you to stay consistent in the gym, plus you’ll be able to track your progress and stay motivated for months to come. Sounds good, doesn’t it?
Take your time
How should you attack your 12-week gym workout plan? A common mistake I see time and time again, even among experienced gym- goers, is to go out with all guns blazing from day one of the training programme, forgetting to take the necessary number of rest days. This is counterproductive to your aims as it will eventually mean that you’ll have to miss key sweat sessions due to delayed onset muscle soreness (DOMS) and/or mental fatigue. Don’t fall into that trap! Rest days are there for a reason, so use them.

The same advice applies to lifting heavy weights – don’t increase the weight before your body is ready to do so. Let me paint a picture as to why this matters. Gym-goer A has two leg-focused weights sessions planned, one on Monday and one on Thursday. She pushes herself to lift as much as possible on Monday, leaving the gym feeling accomplished and high on endorphins. But by Thursday, her legs still feel under-recovered and she can only cope with lifting 50 per cent of Monday’s weights.
Clearly, Gym-goer A would benefit more from having aimed for 60-70 per cent of her training weight capacity for the first few sessions, to give her legs a chance to adapt to the load. Heed this warning and be mindful with your weight selection!
Get fit in 12 weeks
Now, you want to get with the programme but you need a plan to follow. This 12-week gym workout plan is for everyone, as it focuses on improving all components of fitness, including cardiovascular capacity and strength. In it, you’ll find compound (multi-muscle) exercises – squats, presses and pulls – throughout the entire 12-week period. This is so you can build full-body strength by doing demanding moves that offer the biggest muscle recruitment bang for their exercise buck.
You’ll also find ‘accessory’ (smaller muscle recruitment) moves, which are important for enabling you to increase training volume and to target specific muscle groups. The reps change every four weeks to keep things interesting and continue challenging your muscles. It’s a good idea to have some form of short-term and long-term goal before you get started. This will help to keep you going and
also increase the likelihood of your training continuing when the 12 weeks end.
A good short-term strength goal could be to complete a full push-up unassisted, a good long-term goal could be to complete 10 push-ups without stopping. A good short-term cardio goal could be to run an uphill route on at least one of your weekly cardio sessions, a long-term one could be to run 5K in less than 25 minutes. Ready? Let’s get going…
Your 12-week gym workout plan
This plan is based on doing two strength sessions and two cardio sessions a week – perfect for kickstarting your fitness. Spend 10 minutes warming up before and five minutes cooling down after every session. Be sure to select the right version of the workout each week (see overleaf), as the number of reps, sets and moves progresses to keep your muscles challenged.
Training tips
Keep progressing. You can do this by changing the volume, frequency or intensity of exercise. This ensures your body stays challenged.
During this 12-week gym workout plan, if the number of reps of a given exercise decreases or remains the same as the previous month, increase the weight as this will keep your muscles tested.
Take progress pictures to track your physical results. These can be great for motivation. Aim to take a photo of the front, back and sides of the body, first thing in the morning before eating and on the same day each week.

- Extend your left leg behind you so your toes are resting on the bench.
- Keeping hips and shoulders square, torso upright, slowly lower into a lunge as you drop your left leg towards the floor.

- Hold the handles with an overhand grip.
- Take a few steps back, until your arms can fully extend in front of you with the cable taut.
