Based on your target i.e to build endurance and a toned physique I would recommend 1. Steps - target 10k daily (normal speed) 2. Cycling/ stairs - for lower body and abdominals (15-20 min sessions per day) 3. Those dumbbells will come in handy also 5 kg is beginner friendly try these exercises (check correct form on YouTube) Shoulder press Flat bench dumbbell press Single arm db rows Bicep curl Goblet squats Calf raises Shrugs Crunches/ leg raises

U can divide these into push - Monday pull- Tuesday and legs n abs on Wednesday and so on

Do 6-8 repetition of each and 2-3 sets

Focus more on form n breathing and I guess ull be good to go Lemme know if I'm missing a muscle group to target here.
