Programming tips

Tần suất:

• Beginner: 1-2x/tuần arm direct
• Intermediate: 2-3x/tuần
• Advanced: 3-4x/tuần varied volume

Volume per tuần:

• Bicep: 12-20 sets
• Tricep: 12-20 sets
• Track + progressive

Rest:

• Compound: 2-3 phút
• Isolation: 60-90s
• Pump work: 30-45s

Intensity:

• 70-85% 1RM strength

• 40-60% 1RM pump

Progression strategies

Tuần 1-2: Linear

• Add 1.25-2.5kg / week per exercise

Tuần 3-4: Volume

• Add set per exercise
• Same weight

Tuần 5-6: Intensity

• Avoid: momentum + speed

Time under tension (TUT):

• 30-60s set duration ideal hypertrophy

Skip stretching	Mobility post-workout

Recovery + Rest

Giấc ngủ:
