Overview
Plan and time your stretching routine by configuring hold times, sets, and rest periods for each stretch. This calculator helps you build a systematic stretching program following exercise science guidelines.
Formula
Total Stretching Time = Sum(Hold Time per Exercise × Sets) + Sum(Rest Between Exercises) Recommended Hold Times: • Static Stretching: 15–60 sec per exercise • Dynamic Stretching: 10–15 reps per exercise • PNF Stretching: 6 sec contraction + 30 sec relaxation ACSM Guidelines: • At least 2–3 times per week • Hold each stretch 15–60 seconds • 2–4 sets per exercise
How to Use
- 1Add stretching exercises to your routine.
- 2Set the hold time in seconds for each exercise (e.g., 30 sec).
- 3Set the number of sets (e.g., 2 sets).
- 4Set the rest time between exercises (e.g., 10 sec).
- 5The total routine duration is calculated automatically.
Tips
- ✔Perform dynamic stretching before exercise and static stretching after exercise.
- ✔Hold static stretches for at least 15 seconds to gain flexibility benefits.
- ✔Stop immediately if you feel pain — you should feel only a mild pulling sensation.
- ✔Breathe deeply and exhale to progressively increase stretch range rather than holding your breath.
- ✔Consistent stretching (3+ times per week) for 4–6 weeks is needed for meaningful flexibility gains.
FAQ
Q. How long should I stretch?
ACSM recommends holding each stretch for 15–60 seconds and repeating 2–4 sets. A typical full-body stretching routine takes about 10–15 minutes. For flexibility improvement, holding for 30 seconds or more is more effective.
Q. Is static stretching before exercise really bad?
Recent research shows that prolonged static stretching (over 60 seconds) immediately before exercise can temporarily reduce strength and power output. Dynamic stretching (leg swings, arm circles, etc.) is recommended pre-workout, while static stretching is best reserved for cool-down.
Q. What is PNF stretching?
PNF (Proprioceptive Neuromuscular Facilitation) is an advanced stretching method using contract-relax techniques. It involves a 6-second isometric contraction followed by 30 seconds of relaxation and stretching. It is considered the most effective flexibility method but is safer with a partner.
