Training Basics.
The core concepts behind how Checkfit trains you.
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.
