The biggest barrier to starting the gym isn't fitness level. It's not knowing what to do once you're inside. You walk in, look at the equipment, and freeze. Where do you start? Which machine is which? What weight is safe? How many reps?
Most people ask a gym staff member. Some ask a friend. A few join a class. But most—the majority—just leave and don't come back.
If you knew exactly what to do on your first day, week one becomes easy. Knowing removes anxiety. This is your week-one gym programme for PureGym, Anytime Fitness, or any UK leisure centre.
A step-by-step first week at a UK gym, done on actual machines with exact weights and exact reps, builds enough confidence to come back for week two—and week two is when strength actually starts growing.
What PureGym UK Actually Has and Which Equipment Matters for Beginners
Walk into any PureGym in the UK. You'll see:
The cardio section. Treadmills, bikes, rowing machines, stair climbers. Ignore this for week one.
The machine weight section. Leg press, chest press, lat pulldown, leg curl, shoulder press, cable machines, seated row. This is where you start.
The free weight section. Dumbbells (5kg to 50kg+), barbells, squat racks, benches. This is intermediate and advanced.
The functional area. Pull-up bars, TRX straps, cable machines, medicine balls. Advanced stuff.
As a beginner, your week-one gym programme uses the machine weight section only. Machines are safer because you don't have to balance the weight. The movement path is fixed. You learn movement without having to stabilise.
At a typical PureGym, the main machines you need are:
- Leg press machine (usually bright blue or red, large seat, push legs away from you)
- Chest press machine (usually opposite the leg press, push handles away from you)
- Lat pulldown machine (overhead pull-down, usually in the cardio area or behind the main machines)
- Leg curl machine (lies on stomach, pull weight up toward glutes)
- Seated row machine (sit facing handles, pull toward you)
That's it. Five machines. That's your entire first week.
The Five Movements That Cover the Whole Body—Named and Located on the Gym Floor
Movement 1: Leg Press Machine
Location: Usually at the back of the main machine section, big upright machine with a large seat.
Function: Strengthens quads (front thigh), glutes (backside), hamstrings (back thigh).
How to use: Sit in the seat. Place feet on the platform in front of you, about hip-width apart. Push the platform away from you until legs are nearly straight (don't lock knees). Slowly bend your knees and bring the platform back toward you. That's one rep. Do this 8 times, rest 2 minutes, repeat three times total.
Weight selection: On your first session, pick a weight where your 8th rep feels moderately hard. You should be able to finish all 3 sets. If you complete it easily, next week add 2–5kg.
Movement 2: Chest Press Machine
Location: Usually near the leg press or in the main machine area, facing outward or upward depending on the gym.
Function: Strengthens chest (pectorals), shoulders (anterior deltoid), triceps (back of arms).
How to use: Sit with your back against the pad. Grab the handles at roughly shoulder height. Push the handles away from you until arms are nearly straight. Slowly bring them back toward you. That's one rep. Do 8 reps, rest 2 minutes, repeat three times.
Weight selection: Same rule—pick a weight where your 8th rep feels hard but doable. Next week, add 2–5kg.
Movement 3: Lat Pulldown Machine
Location: Usually in a corner or against a wall, overhead cable machine with a lat bar (long bar) at the top.
Function: Strengthens back (latissimus dorsi), shoulders, biceps (front of arms).
How to use: Sit facing the machine. Grab the bar with hands wider than shoulder-width. Pull the bar down to your upper chest (not all the way to your stomach). Slowly let it back up, arms straightening. That's one rep. Do 8 reps, rest 2 minutes, repeat three times.
Weight selection: Same—find a weight where rep 8 is hard.
Movement 4: Leg Curl Machine
Location: Usually near the leg press, a machine you lie face-down on.
Function: Strengthens hamstrings (back thigh).
How to use: Lie face-down on the machine. Your knees should be just at the edge of the pad. Curl your legs upward, bringing your heels toward your glutes. Slowly lower back down. That's one rep. Do 10 reps (higher rep range), rest 2 minutes, repeat two times total.
Weight selection: This is an accessory movement (not a main lift), so lighter weight than the big three. Pick something that allows 10 reps.
Movement 5: Seated Row Machine
Location: Usually in the main machine area, machine you sit on facing handles.
Function: Strengthens back (rhomboids, lats), shoulders, biceps.
How to use: Sit at the machine. Grab the handles. Pull them toward your torso (your elbows should bend and move backward). Slowly let them extend back. That's one rep. Do 8 reps, rest 2 minutes, repeat three times.
Weight selection: Same as movements 1–3.
These five machines hit every major muscle group. You don't need anything else for week one.

You've now done this three times. You know where everything is. You know your starting weights. You're ready for week two.
According to NHS physical activity guidelines, three resistance training sessions per week producing measurable neuromuscular adaptations—you'll feel less clumsy and more coordinated after this week.
The Mistakes Beginners Make on the Gym Floor in Week One
Mistake 1: Picking weight too heavy.
Ego says "I'll start with 50kg." Your body says "I can't do 8 reps of that." You do 6 reps, fail, feel weak, quit.
The fix: Start conservatively. You can always go heavier next week. Starting too light is forgivable. Starting too heavy is injury risk.
Mistake 2: Not resting long enough between sets.
You do a set of 8 reps, rest 30 seconds, do another set. Your nervous system isn't recovered. The second set is weaker. You're not getting full benefit of the stimulus.
The fix: Rest 2 minutes between sets on your main lifts (movements 1–3). This allows your nervous system to recover. You'll be noticeably stronger on your second set.
Mistake 3: Changing weight every session.
You do leg press Monday at 50kg. Wednesday you try 60kg. Friday you go back to 50kg. You're not building progression; you're fluctuating.
The fix: Pick a weight that works on Monday. Do the exact same weight Wednesday and Friday. Only increase it the following Monday. This builds a pattern of progression.
Mistake 4: Not tracking what weight you used.
You do leg press Monday, forget the weight you used. Wednesday you guess. Friday you guess again. You have no idea if you're progressing because you don't remember your baseline.
The fix: Write it down. Phone notes app is fine. "Monday leg press: 60kg × 8 reps, 3 sets."
Mistake 5: Doing too much accessory work.
You see someone doing cable flyes, lateral raises, bicep curls, tricep extensions. You think you should do those too. You add five more exercises. Your session is now 90 minutes. You're fatigued. You quit the next week.
The fix: Stick to the five machines above for all of week one. That's it. Accessories come later.
How to Progress from Week One Without Guessing
Week one is about learning. Week two onwards is about progression.
Week two progression:
Same movements, same number of sets and reps, add 2–5kg to every main movement (movements 1–3). If you did leg press at 40kg Monday, do 42kg Monday of week two.
Week three progression:
Same as week two. The goal is adding weight every week. If leg press is 42kg, try 44kg this week.
Week four progression:
At the end of week three, ask yourself: could I have added another rep on my last set? If yes, the weight is slightly light now. Add 4kg for week four. If no (you're struggling), keep the same weight.
This is linear progression. Every week you add 2kg (or attempt to). By week 12, you've added 20kg. That's real strength progress. NHS strength training guidance recommends muscle-strengthening activity on at least two days per week — three sessions gives you the extra frequency that makes these weekly progressions compound.
The machines display the weight clearly (a pin you insert into the weight stack). This makes progression obvious and trackable. You see 40kg, 42kg, 44kg on your phone notes. You know you're getting stronger.
Frequently Asked Questions
Q: What if I don't know how to use a machine?
Ask a gym staff member. Every gym has an induction where they show you equipment. If not, most YouTube tutorials show the exact movement. Watch a 2-minute video and you'll understand.
Q: Should I stretch or warm up before starting?
Light warmup (2–3 minutes on a treadmill or stationary bike) or 5–10 minutes of mobility (arm circles, leg swings, light cardio movement) is fine. You don't need to. Jumping straight to the leg press machine is okay, especially as a beginner.
Q: What if the machines are busy?
Go at a different time. Most gyms are quiet at 6–7am or 2–3pm on weekdays. Peak hours (5–7pm) are busy. For your first week, pick a quiet time to reduce anxiety.
Q: Should I do cardio in week one?
No. Just strength training for week one. Cardio can come later. Your job this week is to learn the machines and build habit. One task at a time.
Q: How much should I eat before the gym?
Eat normally. If you're training at 6am, have a banana 30 minutes before. If you're training at 5pm, eat normally at lunch, maybe a snack at 4pm. You don't need special pre-workout nutrition.
Q: What if I'm too sore to come back on Wednesday?
Come back anyway. The soreness (DOMS—delayed onset muscle soreness) is worst on day 2–3 and goes away by day 4. Light movement (like your week one gym session) actually speeds recovery. Don't skip because of soreness.
Q: Should I do anything on rest days (Tuesday, Thursday)?
Light movement is fine (walking, stretching, yoga). But don't do strength training. Your muscles recover on rest days. This is when adaptation happens.
Q: Is one week at these machines enough before trying free weights?
Yes. If you feel confident on Wednesday of week one, you can try a free weight version of one exercise (dumbbell squat instead of leg press, for example) in week two. But the machines are safer for the first week, so stick with them.
Q: How long until I see results?
You'll feel stronger by day 4 (week two). You'll notice clothes fit differently by week 4. You'll see visible muscle by week 8. Strength gains (what you can lift) show up in week 2–3.
