Been at the gym most mornings before work and swimming most nights after work for about 8 weeks now, I wouldn't say I've been hitting it hard until this week when I started to look into supplements and different styles of workouts. At the moment I'm aiming to cut my body fat, so I've started to do weight training (various exercises 8-10 reps) followed by HIIT for around 20-30 minutes, really looking forward to seeing the results. Are there any decent exercises I can add into my HIIT sessions to vary things up a little, at the moment I'm on the treadmill with a sprint for 1 minute and 30 seconds at lower pace, repeated 4-5 times. I then go to the rowing machine and max out for 20 seconds and rest for 10 seconds, I enjoy doing weighted steps for the same intervals as the rowing machine. I attempt to do press ups for 20 seconds and resting for 10 seconds but thats not going as well as the others. To finish off I then move onto some core exercises with the same intervals as above.
