The Most Effective Weight Training, Cardio & Nutrition for Women | Dr. Lauren Colenso-Semple

What It Covers

Dr. Lauren Colenso-Semple, PhD in integrative physiology and certified strength coach, explains evidence-based resistance training, cardiovascular fitness, and nutrition protocols for women. She addresses how hormone cycles, menopause, and birth control impact training adaptations, debunking common myths about sex-specific programming while providing actionable guidance on sets, reps, rest periods, and training frequency for optimal muscle growth and strength.

Key Questions Answered

• •Training Frequency and Volume: Women should perform full-body resistance training two to three days per week, targeting all major muscle groups with at least two sets per muscle group, preferably three, but no more than four sets per exercise. For those training two to three days weekly, full-body sessions work best. Training four days allows upper-lower splits, while five to six days permits more specialized splits focusing on specific muscle groups each session.
• •Repetition Ranges and Failure Training: Muscle growth occurs across a wide repetition range from six to twelve reps, provided sets are taken close to failure, meaning stopping one to two reps before complete inability to perform another rep. Lower rep ranges like three to five require significantly more total sets to achieve equivalent volume. Beginners should start with eight to twelve reps to develop proper movement patterns through sufficient repetition practice before exploring lower or higher ranges.
• •Rest Intervals and Supersets: Standard rest periods of two minutes between sets suffice for most exercises, with three minutes appropriate for compound movements like squats and deadlifts. To maximize time efficiency, pair agonist-antagonist exercises like bench press with rows in supersets, alternating between push and pull movements without compromising adaptation or performance. This approach prevents phone distractions while maintaining workout effectiveness and reducing total session time.
• •Menstrual Cycle and Training: Research shows no need to modify training programs based on menstrual cycle phases. Seventy-five to eighty percent of women report menstrual symptoms, yet none report changing training in response. Hormone fluctuations during the cycle do not affect muscle protein synthesis, growth response, or performance capacity. Women should train consistently and progressively, adjusting only if experiencing significant symptoms that genuinely impair workout quality or recovery.
• •Fasted Training and Meal Timing: Long-term studies demonstrate identical muscle growth and fat loss adaptations whether training fasted or fed in both men and women. The decision should be based purely on personal preference and digestive comfort. Post-workout protein synthesis remains elevated for twenty-four hours after resistance training, eliminating the need for immediate post-workout nutrition within a narrow anabolic window. Consuming protein within three hours post-training provides equivalent benefits to immediate consumption.
• •Hormonal Contraception Effects: Combined oral contraceptive pills do not significantly impact strength, hypertrophy, or power adaptations to resistance training. Since natural endogenous hormone fluctuations across the menstrual cycle do not affect training adaptations despite being substantial, the synthetic hormones in contraceptives similarly show no meaningful effect on exercise performance or muscle growth. Women on hormonal contraception should follow identical training protocols as those not using contraception.
• •Progressive Overload and Movement Quality: Beginners should spend two to three weeks learning proper movement patterns and full range of motion before aggressively pursuing progressive overload. Adding repetitions proves more sustainable than constantly increasing weight, which often leads to compromised form and reduced range of motion. Moving weights as quickly as possible during the concentric phase under control, rather than intentionally slowing tempo, optimizes neural adaptations and strength development across all experience levels.
