In this concise fitness advisory video, Eric Roberts explains how rest intervals between weight‑training sets should vary according to the trainee’s primary goal. For cardio and endurance, he recommends short rests of 30–60 seconds. For muscle hypertrophy and strength, he cites current research suggesting a minimum of 90 seconds, often extending to 2–5 minutes, to avoid excessive fatigue that compromises load and effort. He notes that consistently needing less than 90 seconds of rest signals the need to increase weight. Finally, he argues that fat‑loss programs should prioritize muscle‑building work combined with a calorie deficit, because greater muscle mass raises overall energy expenditure. The video ends with a call‑to‑action to obtain a free workout program via a link in his bio.
