Training Basics.

The core concepts behind how Checkfit trains you.

14 answers
How many days a week should I train? +

Three to five for most people. The best schedule is the one you'll actually keep — consistency beats the perfect split every time.

Should I train to failure? +

Rarely. Training 1–3 reps shy of failure builds nearly the same muscle with far less fatigue — that's why your program prescribes RIR instead of grinding every set.

How long should I rest between sets? +

Two to three minutes on big lifts, one to two on isolation work. Rest enough to actually hit your rep target — rushing costs more than it saves.

Do I need to be sore for a workout to count? +

No. Soreness is a poor signal of growth. Progression — more reps, more weight, over weeks — is the signal that matters.

Why am I weaker some days? +

Sleep, stress, food, and time of day all move performance a few percent. That's normal, and it's exactly what rep ranges are for.

Can I do cardio alongside lifting? +

Yes. Low-intensity cardio fits anywhere; keep hard cardio away from leg days when you can. It supports recovery and health more than it costs you muscle.

How fast will I see results? +

Strength moves within weeks. Visible muscle takes months. The people who get both are the ones still logging in month four.

Heavy weights or light weights for muscle? +

Both build muscle when sets approach failure. Lower reps bias strength, higher reps are joint-friendlier — your program uses the range that fits each lift.

What should I eat before training? +

Something with carbs and protein one to three hours out. Training fasted is fine if you feel strong; performance is the tiebreaker.

How much does sleep matter? +

More than any supplement. Seven to nine hours is where recovery, strength, and appetite regulation live.

What do I do about a plateau? +

First, trust the system — deloads and volume adjustments exist for this. Then audit the unglamorous stuff: sleep, protein, effort honesty. Plateaus are usually one of those three.

Do I need supplements? +

Food first. The two with real evidence are creatine monohydrate and protein powder for convenience. Everything else is optional at best.

Are machines worse than free weights? +

No — both build muscle. Free weights train more stability; machines isolate with less setup. A good program uses whichever fits the goal and your equipment.

Is lifting safe? +

With controlled technique and loads you've earned, it's one of the safest ways to train — and the strength it builds protects you everywhere else. Form cues ship with every exercise.
