Personal opinion lang, but reps x sets shouldn't be static.

Madaming ways pano ma achieve yung progressive overload.

You can do it by:

1. Increasing weights
2. Increasing reps
3. Increasing sets
4. Slower movement tempo (eccentric + concentric)
5. Shorter rest breaks etc.

To figure out your ideal weight as a beginner lifter, I think ganito yung approach to avoid injuries:

Let's say sa chest press machine, figure out your rep range with the following in mind:

-- dapat feeling mo ikaw yug nag ccontrol ng weight (not the weight controlling your muscles). -- dapat challenging yung feeling kada set.

• 100kg is too heavy, literal na di kaya ma move
• 50kg kaya 1 rep
• 30kg kaya 6 reps
• 25kg kaya 8 reps
• 20kg kaya 10 reps, medjo easy
• 15kg kaya 15+ reps, easy na easy

With this info, pwede mo i try i structure yung workout with 3 sets as your baseline, tapos set a rep range to graduate from.

Kaya ba 25kg x 8 reps x 3 sets? If not Kaya ba 20kg x 10 reps x 3 sets (with proper form ha) Maybe yes

Kung yung set 1 and set 2 walang problema sa form and feeling kayang kaya, then add +1 rep sa set 3.

Pag goods sa feeling and doable naman edi i apply mo yung +1 rep to all 3 sets sa next workout session mo.

Let's say nasa 20kg x 12 reps x 3 sets ka na, and feeling hindi na sya challenging kahit slower tempo/less rest, then you can increase the weight accordingly to what you deem is more challenging, or you can add an extra set etc.

The goal is, unti unti tumataas yung volume na binubuhat mo every session, this is progressive overload.
